Answer: x = -3
Step-by-step explanation:
Given
-7x - 14 = 2x + 13
Subtract 2x on both sides
-7x - 14 - 2x = 2x + 13 - 2x
-9x - 14 = 13
Add 14 on both sides
-9x - 14 + 14 = 13 + 14
-9x = 27
Divide -9 on both sides
-9x / -9 = 27 / -9
[tex]\boxed {x = -3}[/tex]
Check:
Left-hand side = -7x - 14
= -7 (-3) - 14
= 21 - 14
= 7
Right-hand side = 2x + 13
= 2 (-3) + 13
= -6 + 13
= 7
7 = 7
Hope this helps!! :)
