Solve this set of simultaneous equations. 1. 4x+2y=12 2. 2x+3y=10

To solve simultaneous equations we need to make either the y coefficients or the x coefficients equal so that we can cancel them out. For this set of equations we are going to make the x coefficients the sam...

Expand and simplify 3 (y + 4) - 2 (4y + 1)

3 (y + 4) - 2 (4y + 1)= 3y + 12 - 8y - 2= (3y - 8y) + (12 - 2)= 10 - 5y
