Question

Can anyone help me please?

Answer 1

Plug in (-1, 3) into both equations

Ax - 2y = 4

A(-1) - 2(3) = 4

-A - 6 = 4 Add 6 on both sides

-A = 10 Divide -1 on both sides

A = -10

5x + By = -1

5(-1) + B(3) = -1

-5 + 3B = -1 Add 5 on both sides

3B = 4 Divide 3 on both side

B =
`(4)/(3)`
