Answer:
C. 47
Step-by-step explanation:
5(8 + 7)
Expand the brackets. Brackets mean to multiply.
5(8 + 7)
5 * 8 + 7
= 40 + 7
= 47
Use substitution.
y = 2 - x and y = 4x + 7 can become
2 - x = 4x + 7
Now solve for x
-5 = 5x
-1 = x
Now plug -1 for x in either equation.
y = 2 - x -> y = 2 - (-1) -> y = 3
y = 4x + 7 -> y = 4*-1 + 7 -> y = -4 + 7 -> y = 3
So C) is the correct answer.
