80-3x=56, Subtract 80 from each side:
-3x = 56-80
-3x=-24
x will equal 8, hope this helps! Have a BLESSED day! :-)
Everything should add up to 100%. So do

Write the area of the rectangle as a sum: x²＋3x＋2x＋2×3
Write the area of the rectangle as a product: (x＋3)(x＋2)
Write an equation showing each the expressions above are equal: x²＋3x＋2x＋2×3＝(x＋3)(x＋2)
x²＋3x＋2x＋6＝x²＋2x＋3x＋6
This statement is true for any value of x, because both sides are identical.
Hope my answer helped u :)
