Question

can someone explain step by step to solve system equations and example ill show here 3x+4y=-2 x=-2y

Answer 1

the simplest way for this example is to use substitution.
sub x = -2y into 3x+4y = -2
3(-2y) + 4y = -2
-6x + 4y + -2
-2y = -2
y = 1
then since x = -2y
x = -2(1) = -2

Answer 2

so u simplify them and divide and basically is the answer.
