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.

Notice how both expressions are equal to x?
That means they must be equal to each other.
Thus choice D is the answer.
