given the diagram below, find the value of x if the area of the rectangle is 78 square meters .

x = 6

Step-by-step explanation:

You want to find factors of 78 that differ by 7. The value of x is the smaller of them.

78 = 1·78 = 2·39 = 3·26 = 6·13

We see the last factors on this list differ by 7, so we conclude x = 6.

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x
