Question

Solve 3x+2y=1 and 2x-3y=3 in cross multiple method

Answer 1

There are 4 main methods of solving system of linear equations. These method .... Step 3: Cross multiply the terms so written below x, y and 1. .... Solution: 2x + 3y = 17 and 3x - 2y ... x = 7 - y --------- (1) (2) 2x - 3y = 11 2(7 - y) - 3y = 11 14 - 2y - 3y = 11 14 - 5y = 11 -5y = 11 - 14 -5y = -3 y = \frac{3}{5}
