To sub, solve for 1 variable
solve for y
14-4x=2y
divide by 2
7-2x=y
sub 7-2x for y
(7-2x)+2x=7
7-2x+2x=7
7=7
true

Answer:Given a rectangle, the general equation for the perimeter is P=2l+2w and area is A=lw where l is the length and w is the width.
Let x = width and x+10 = length
So the equation to solve becomes 40=2x+2(x+10) so x=5 thus the width is 5m and the length is 15m.
Thus the area is 5⋅15=75m2
