8x-7y=42
24x+y=170
An easy way to begin is to solve for one variable in one of your two equations. I will use the second equation to solve for y:
24x+y=170
y=170-24x
This solution for y will then be plugged into the first equation so the equation will be of one variable, and therefore solvable:
8x-7y=42
8x-7(170-24x)=42
8x-1190+168x=42
176x=1232
x=1232/176=7
x=7
The solution we made for y can now be used with the solved value of x to find y's numerical value.
y=170-24x
y=170-24(7)
y=170-168
y=2
So, finally, we get that x=7 and y=2
