Question

If you were to use the substitution method to solve the following system, choose the

new equation after the expression equivalent to x from the second equation is
substituted into the first equation.

2x-3y=-29
X+4y=13

Answer 1

15x - y = - 6.....15x + 6 = y...so we sub in 15x + 6 in for y on the other equation

5x - 3y = -13

5x - 3(15x + 6) = -13 <== the new equation
