b. Add five to both sides.
c. Multiply by sides by 3/4
d. Subtract 5 from both sides.

Answers

Answer:

a. Multiply both sides by 4/3

Step-by-step explanation:

Since you're dealing with a fraction, multiplying both sides by the reciprocal, which is the fraction flipped, it could cancel out the fraction so now x is alone on one side.

[tex]7-12+6x-10x[/tex]

Now, combine like terms

Please help me find x

Answers

Answer:

x=13

Step-by-step explanation:

According to the question

3x+5x-14=90

8x-14=90

8x=90+14

8x=104

x=104/8

x=13

180 = 90 + 3x + 5x - 14
180 - 90 + 14 = 3x + 5x
104 = 8x
104/8 = x
x = 13

Checking:
3(13) + 90 + 5(13) - 14 = 180
180 = 180
So x=13
