Question

Using the substitution method, Vito is solving the following system of equations algebraically: y + 3x = -4 2x-3y = -21% D Which equivalent equation could Vito use?

Answer 1

Answer:

He could use y+3x=-4

Step-by-step explanation:

When we subtract 3x on both sides, we get y=-4-3x, which means we just solved a variable and can substitute into the other equation 2x-3y=-21
