Answer: 25
Equation:
2(7)+2(x)=64
14+2x=64
2x=64
X=25
Hope this helps :)
The slope intercept form of that equation would be y = 1/2x + 1. 1 would be the y-intercept, and 1/2 would be the slope. If you are looking for the answers to y and x, you would need another equation containing those variables to figure that out.
