Answer: X=1

Step-by-step explanation:

Add 7x over to the 4x to get 11x. 11x+8=19 subtract 8 on both sides to get 11x=11. Divide and you get 1.

Answer:

x = 1

Step-by-step explanation:

4x + 8=-7x +19

add 7x to both sides

4x + 7x+8=-7x+7x +19

11x + 8=19

subtract 8 from both sides

11x + 8-8= 19-8

11x=11

x = 1
