Question

8x+9=3(x-1)+7
pls write full method how did u done that​

Answer 1

Answer:

8x + 9 = 3(x-1) + 7

Distribute 3 through the parenthesis.

8x + 9 = 3x + 3(-1) + 7

8x + 9 = 3x - 3 + 7

8x + 9 = 3x + 4

subtract 3x from both sides

5x + 9 = 4

subtract 9 from both sides

5x = -5

divide both sides by 5

x = -1
