Match the steps and the reasons to solce the system of linear equations algebraically.

Question

4x - 9y = 5
y = 3

Answer 1

Steps:
1. Substitute y = 3 into the first equation.
2. Solve for x.
3. Substitute the value of x back into one of the original equations to find the value of y.

Reasons:
a. Substituting y = 3 into the first equation eliminates one variable and simplifies the equation.
b. Solving for x will give the value of one of the variables.
c. Substituting the value of x back into one of the original equations allows us to solve for the second variable.
