Question

Solve: 4x - 3y = -1
3x - 2y = 0

Answer 1

Just multiply both equations
3*(4x - 3y) = 3*(-1) => 12x -9y = -3
4*(3x - 2y) = 0 => 12x -8y = 0

Now subtract the first from the second:
y=3

Then substitute y=3 in one of the previous equations to find x=2

Answer 2

First try to make one of the variable equal in both of the equation . let's make 'x'.
3(4x-3y)=(-1)3
4(3x-2y)=(0)4
=>12x-9y=-3
12x-8y=0
now, subtract & solve:)

Answer 3

My method is called elimination method.
