Solve the system by graphing. 2x-2y=5 y=x-4

Convert 2x-2y=5 into y=mx+b
-2y=-2x+5
Divide all by -2 to get the Y-intercept and Slope.
y = x-2.5
The slope is 1, and the Y-Intercept is -2.5

y=x-4 is already in y=mx+b, so just graph this one.
The slope is 1, Y-Intercept is -4.
The graphs are listed in the picture.

Step 1. When there is a in front of an expression in parentheses, change the sign of each term in the expression-> -11 + 5 - 9 - (-13) - (-5)
Step 2. When there is a in front of an expression in parentheses, change the sign of each term in the expression-> -11 + 5 - 9 + 13 - (-5)
Step 3. When there is a in front of an expression in parentheses, change the sign of each term in the expression -> -11 + 5 - 9 + 13 + 5
Step 4. Calculate the sum or difference
The ANSWER is 3 .
