Question

Solving systems by elimination 3x + 4y equals -3 5x + 3y equals 6

Answer 1

3x+4y=-3......(1)
5x+3y=6........(2)

So we multiply equation 1 by 5 and 2 by 3 and subtracting, we got

15x+20y=-15
15x+9y=18
(-) (-) (-)

11y=-33
y=-3

Putting y=-3 in equation 1, we have 3x-12=-3
3x=9
x=3

So x=3(Ans)
y=-3(Ans)

Answer 2

Answer:

Move all terms that don't contain  x  to the right side and solve.

x=−1  −  4y/3

Move all terms that don't contain  x  to the right side and solve.

x=6/5  −  3y/5
