Question

what is the answer to this question? I'm a bit stumped. Also how do I do it? 5(x - 4) = 2(x + 5)

Answer 1

x = 10

Explanation:

5(x - 4) = 2(x + 5)

Distribute on both sides

5x-20 = 2x+10

Subtract 2x from each side

5x-20-2x = 2x+10-2x

3x -20 = 10

Add 20 to each side

3x-20+20=10+20

3x= 30

3x/3 = 30/3

x = 10
