y = -2X +1
4x + 2y = -2
2 answers:
Answer:
Step-by-step explanation:
4x + 2(-2X +1) = -2
Order of operations -
4x + -4x +2 = -2
Combine terms
4x-4x=0x
2 = -2
Answer:
no solution
Step-by-step explanation:
y = - 2x + 1 → (1)
4x + 2y = - 2 → (2)
substitute y = - 2x + 1 into (2)
4x + 2(- 2x + 1) = - 2 ← distribute parenthesis and simplify left side
4x - 4x + 2 = - 2 ( subtract 2 from both sides )
0 = - 4 ← not possible
this indicates the system of equations has no solution
