Elowyn is using the substitution method to solve the system of equations shown below.

Question

She substituted the first equation into the second equation for y.
What is Elowyns result after simplifying and combining like terms?
1. y = -3x
2. 6x + 4y = 12

Answer 1

1. y = -3x
2. 6x + 4(-3x) = 12
3. 6x - 12x = 12
4. -6x = 12
5. x = -2

After simplifying and combining like terms, Elowyn found that x = -2.
