Question

5x-2y=42

-3x+2y=-26
which of the following shows the results of the two equation added together?

Answer 1

Explanation:

When we add the two equaions, y will be cancelled becaue -2y + 2y = 0.

Thus we can find the value of x.

5x - 2y = 42 -----------(I)

-3x + 2y = -26 {Now add}

2x = 16

x = 16/2

x = 8
