{2x−4y=−63x+2y=−1

Drag and drop the answers into the boxes to match each step.

Answer 1

Explanation:

1). 6x - 12y = -18

6x + 4y = -2

Multiplication property of equality.

2). -16y = -16

Substitution property of equality.

3). y = 1

Division property of equality.

4). 2x - 4(1) = -6

Substitution property of equality.

5). 2x - 4 = -6

Simplify.

6). 2x = -2

Addition property of equality

7). x = -1

Division property of equality
