Question

4x + y = 3
x - y = 2


Which equation(s) best represent the *Second step* of solving the system above?

A. 2x-x= x-7

B. 2xy - 7 = 2

C. 4(2 + y) + y = 3

D. 4x + (-2 + x) = 3​

Answer 1

Answer:

C

x-y=2.turn into x=2+y

plug it in the other equation

x is 2+y

so

4(x)= 4(2+y)

4(y+2)+y=3
