Two solar panels were installed side-by-side on a roof, 18 feet in total. one panel is 3.4 feet wider than the other. find the width of each panel.

7.3 feet, 10.7 feet

Step-by-step explanation:

Using one variable and an expression, we can set the width of the two panels equal to the total width and solve:

first panel width = x

second panel width '3.4 wider' = x + 3.4

x + x + 3.4 = 18

Combine like terms:  2x + 3.4 = 18

Subtract 3.4 from both sides:  2x = 14.6

Divide by 2:  x = 7.3

first panel = 7.3 feet

second panel = 7.3 + 3.4 = 10.7 feet
