Answer: 5
Step-by-step explanation:Solving for variable 'x'. 
 
Move all terms containing x to the left, all other terms to the right. 
 
Add '-2x' to each side of the equation. 
7 + 8x + -2x = 37 + 2x + -2x 
 
Combine like terms: 8x + -2x = 6x 
7 + 6x = 37 + 2x + -2x 
 
Combine like terms: 2x + -2x = 0 
7 + 6x = 37 + 0 
7 + 6x = 37 
 
Add '-7' to each side of the equation. 
7 + -7 + 6x = 37 + -7 
 
Combine like terms: 7 + -7 = 0 
0 + 6x = 37 + -7 
6x = 37 + -7 
 
Combine like terms: 37 + -7 = 30 
6x = 30 
 
Divide each side by '6'. 
x = 5 
 
Simplifying 
x = 5
