If 5x - 2y = 6 and 3x + 2y = 10, then find the value of x and y.
Step-by-step explanation:
[tex]\textsf{\large{\underline{Solution}:}}[/tex]
Given Equations:
→ 5x - 2y = 6 ----- (i)
→ 3x + 2y = 10 ---- (ii)
Adding (i) and (ii), we get:
→ 8x = 16
→ x = 16/8
→ x = 2
Substituting the value of x in (i), we get:
→ 5 × 2 - 2y = 6
→ -2y = 6 - 10
→ -2y = -4
→ y = -4/-2
→ y = 2
Therefore:
→ (x, y) = (2, 2) (Answer)
[tex]\textsf{\large{\underline{Verification}:}}[/tex]
Put x = 2 and y = 2 in first equation, the LHS becomes:
= 5 × 2 - 2 × 2
= 10 - 4
= 6
= RHS
Put x = 2 and y = 2 in second equation, the LHS becomes:
= 3 × 2 + 2 × 2
= 6 + 4
= 10
= RHS
Hence, our answer is correct (Verified)
Answer:
X= 2
Y= 2

Y= 1/3X -4
parallel, perpendicular or neither
Answer:
PARALLEL
Step-by-step explanation:
The second equation, y = (1/3)x - 4, has already been solved for y. To compare the slopes easily, we need now to solve the first equation for y, obtaining y = (1/3)x - 4.
We see that these two lines have the same slope, m = 1/3, and thus conclude that these lines are PARALLEL.

Find the value of x.
So you know that all the angles in a triangle must add up to 180. Therefore, you can make this equation:
[tex](-20x+3)+(-40x+18)+(-15x+9)=180[/tex]
And now just solve for x!
[tex]-75x+30=180\\-75x=160\\x=\frac{160}{-75}\\x=-2.4[/tex]
So, your answer is:
x = -2.4
