how do i solve for equations that have 2 variables
Answer:
To solve for an equation with two variables, substitute a zero(0) into the other variable and find one variable.
Step-by-step explanation:
To solve for an equation with two variables, substitute a zero(0) into the other variable and find one variable.
Simple Example:
3x+3y=12
Substitute 0 as y,
3x+0=12
3x=12
12/3=4
x=4
Now substitute 4 into the main equation,
3(4)+3y=12
12+3y=12
-12 -12
3y=0
0/3=0
y=0
So the answer is
3(4)+3(0)=12
12=12

Solye for x
7(x + 1) = 21
Answer:
x = 2
Step-by-step explanation:
Given
7(x + 1) = 21 ( divide both sides by 7 )
x + 1 = 3 ( subtract 1 from both sides )
x = 2
Answer:
x=2
Step-by-step explanation:
7×(x +1)=21
7x +7 =21
7x =21 - 7
7x =14
x=14 :7
x=2
7 ×(2 +1)=21
7 ×3 =21
21 =21

Solve the equation for x
3x + 5 = 14
Answer:
[tex]x=3[/tex]
Step-by-step explanation:
[tex]3x+5=14[/tex]
Subtract 5 from both sides:
[tex]3x+5-5=14-5[/tex]
[tex]3x=9[/tex]
Divide both sides by 3:
[tex]\frac{3x}{3}=\frac{9}{3}[/tex]
[tex]x=3[/tex]

Tanya is 6 times younger than her great-grandfather. If a zero is placed between the digits of her age, it will read as the age of her great-grandfather. How old is Tanya?
Answer:
Tanya is 18 years old.
Step-by-step explanation:
In order to determine this, we assume the following
x = tens digit of the age of Tanya, and also the hundreds digit of Tanya's great-grandfather age
y = units digit of the age of Tanya, and also the units digit of Tanya's great-grandfather age
Therefore, we have:
10x + y = (1 / 6) * (100x + y)
Multiply both sides by 6, we have:
[10x + y] * 6 = [(1 / 6) * (100x + y)] * 6
60x + 6y = 100x + y
Collect the like terms, we have:
6y - y = 100x - 60x
5y = 40x
Divide through by 5, we have:
y = 8x
That is,
8x = y
Note that x and y has to be single digits. This can only be obtained only when x = 1 and y = 8. And given how x and y is defined above, we have:
The age of Tanya = 18
This can be verified as follows:
18 = 108 / 6
18 * 6 = 108
108 = 108
Therefore, Tanya is 18 years old.

what is 75.3% of 1394
Answer:
1049.682 is 75.3% of 1394 or as a fraction is 1049 341/500
Step-by-step explanation:
1394/x=100/75.3
(1394/x)*x=(100/75.3)*x - we multiply both sides of the equation by x
1394=1.32802124834*x - we divide both sides of the equation by (1.32802124834) to get x
1394/1.32802124834=x
1049.682=x
x=1049.682
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{1049.682}}}}}[/tex]
