Mathematics

vodka [1.7K]3 years ago

7 0

Answer:

x = 7 / 2

Step-by-step explanation:

5(2x - 9) + 3 = -7 ---------- subtract 3 from both sides

5(2x - 9) + 3 - 3 = -7 - 3

5(2x - 9) = -10 ------ divide both side by 5

2x - 9 = -2 ---------- add 9 to both sides

2x - 9 + 9 = -2 + 9

2x = 7

x = 7 / 2
