Question 1015002: Thanks in advanced
A student uses the substitution method to solve the system of equations below algebraically.

x = 4y + 5
x = 3y - 2

Which equivalent equation could be used?
a. y = 3(4y + 5) - 2
b. x = 3(4y + 5) - 2
c. x = 4(3y - 2) + 5
d. 4y + 5 = 3y - 2

Last one.
Since they both equal x, set them equal to each other.
