Answer: y = -5
Explanation:
Based on formatting, it's hard to tell what the equations are. But I'm going to assume it's y = 3x - 26 and 2x - y = 19.
First, isolate a variable in one of the equations. I'm going to use 2x - y = 19.
2x - y = 29
2x = 29 + y
y = 2x - 19
Substitute the new y-value into the other equation y = 3x - 26
y = 3x - 26
2x - 19 = 3x - 26
Now solve for x.
-19 = x - 26
x = 7
Plug x = 7 into one of the equations to solve for y.
y = 3x - 26
y = 3(7) - 26
y = 21 - 26
y = -5
