How do i solve this question

a rectangular photograph is 7 inches long and 6 inches wide.
the photograph is framed using a material that is x inches wide. if the area
of the frame and photo

Let's solve your equation step-by-step.    7x+15=2x+19
Step 1: Subtract 2x from both sides.    7x+15−2x=2x+19−2x 
                                                                        5x+15=19

Step 2: Subtract 15 from both sides.    5x+15−15=19−155x=4
Step 3: Divide both sides by 5.                      5x/5=4/5
                                                                             x=4/5
