Answer:
g = -2
Step-by-step explanation:
g = -5r + 13
r = 3
You substitute three for r in the equation.
--------------------------------------------------------------
g = -5(3) + 13
--------------------------------------------------------------
Distribute -5 to 3
--------------------------------------------------------------
g = -15 + 13
--------------------------------------------------------------
Solve
-------------------------------------------------------------
g = -15 + 13
-15 + 13 = -2
g = -2
