The solution to the original system of equations
Solve the system of equations by SUBSTITUTION. (is also, is not)
6y + 5x = 8
x + 3y = - 7
What would your equation look like after the first substitution? (6y + 5(3y - 7) = 8, 6y + 5(- 3y - 7) = 8, 6(- 3y - 7) + 5x = 8, 6(3y + 8) + 5x = - 7)
1 answer
The equation after the first substitution would be: 6y + 5(3y - 7) = 8.
