Drag the tiles to the correct boxes to complete the pairs. Not all tiles will be used. Solve the equations for x and match the solutions.

Solve for each for X.

Step-by-step explanation:

A. 7+2ax=13

1a. Subtract 7 from both sides, 2ax=6

2a. Divide both sides by 2, ax=3

3a. Divide both sides by a, x=3/a

B. -ax-20=-14

1b. flip the signs, ax+20=14

2b. subtract 20 on both sides, ax=-6

3b. divide both sides by a, x=-6/a

C. 4= (6/a)x+5

1c. Multiply both sides by a, 4a=6x+5a

2c. Subtract 5a from both sides, -a=6x

3c. Divide both sides by -1, a=-6x

step-by-step explanation:

area is l × w

the length is 3

and the width is 10
