Answer:
Substitution method is the best to solve system of equations with two variables
x = 1
y = 0
Step-by-step explanation:
-2x + 2 = 4x + (-4)
-2x + 2x + 2 + 4= 4x + 2x - 4 + 4
6 = 6x
x = 1
y = -2(1) + 2
or
y = -4(1) - 4
y = 0
Answer:
x = 1 and y = 0
Step-by-step explanation:
y = -2 x + 2 .......... equation number 1
y = 4 x - 4................... equation number 2
substitute equation number 2 in equ. number 1
4 x - 4 = -2 x + 2
4 x + 2 x = 2 +4
6 x = 6
so x = 1
substitute x= 1 in equation number 2
Therefore y =( 4 × 1) - 4
y = 4 - 4 = 0
therefore x = 1 and y = 0
