Use substitution to solve the system.

y = 3x + 16

4x - 5y = - 25

(-5,1)

Step-by-step explanation:

y=3x+16

4x-5y=-25

substitute the given value of y into the equation.

4x-5 (3x+16) = -25

solve

x=5

substitute the given value of x into the equation.

y=3x (-5) + 16

solve

y=1

(-5,1)

x=-5

y=1

Step-by-step explanation:

4x-5y=-25

4x-5 (3x+16) = -25

-11x-80=-25

-11x-80+80=-25+80

-11=55

-11x/-11=55/-11

x=-5

y=3x+16

y=3 (-5) + 16

y=-15+16

y=1
