Solve the system of equations using substitution.
y = 5x + 5 x = - 3

A.(- 20, - 3)
B.(- 10, - 3)
C.(- 3, - 10)
D.(- 3, - 20)

C. (-3, -10)

Step-by-step explanation:

First label the 2 equations.

y=5x +5 (1)

x= -3 (2)

subst. (2) into (1):

y= 5(-3) +5

y= -15 +5 (expand)

y= -10 (simplify)

Thus, the answer is (-3, -10).
