Math Problem Statement
Solution
Let's solve the system of equations using the elimination method:
Step 1: Multiply the equations to align coefficients
We want to eliminate one variable. Let's eliminate y by making the coefficients of equal. The least common multiple of 8 and 4 is 8, so we multiply the second equation by 2:
Step 2: Add the equations
Step 3: Solve for
Step 4: Substitute into one of the original equations
Using :
