The length of a rectangle is 1 inch less than twice its width, and its perimeter is 40 inches. Find the width of the rectangle.
7 in.
13 in.
14 in.
If the second equation is multiplied by 5 and then the equations are added, the result is _.
x + 5y = 3
2x - y = -2
9x = 13
11x = -7
9x = -7
For the following system, use the second equation to make a substitution for x in the first equation.
x + 3y = 5
x + 7 = 2y
What is the resulting equation?
2y + 2x + 3y = 5
2y + 7 + 3y = 5
2y - 7 + 3y = 5
