Answer:

x=128/3  y=167/3

Step-by-step explanation:

Step 1: Solve y=x+13 for y:

y=x+13

Step 2: Substitute x+13 for y in y=4x−115:

y=4x−115

x+13=4x−115

x+13+−4x=4x−115+−4x(Add -4x to both sides)

−3x+13=−115

−3x+13+−13=−115+−13(Add -13 to both sides)

−3x=−128

-3x/-3=-128/-3

x=128/3

Let's Substitute 128/3 for x in y=x+13:

y=x+13

y=128/3+13

y=167/3 (Simplify both sides of the equation)
