Question

Solve the system of equations below using SUBSTITUTION

1.) 3y=x+12
x=y-4

Answer 1

Answer:

1) x = 0 , y = 4

Step-by-step explanation:

It's already given that x = y - 4

putting the value of x in 3y = x + 12

3y = y - 4 + 12

3y - y = - 4 + 12

2y = 8

y = 8 ÷ 2

y = 4

putting y = 4 in the equation x = y - 4

x = 4 - 4

x = 0

so x = 0 , y = 4
