Eq. 1:
Eq. 2:
Multiply equation 2 by -7:
Eq. 1:
Eq. 2:
Now the coefficients on the y terms are additive inverses.
Add the equations, term by term:
Sum Eq.:
Solve for x:
Substitute this value for x in either equation:
Eq. 1:
Solve for y:
The solution set is the ordered pair (-5,6).
Solve the other systems by the same method. You may have to find multipliers for both equations in some situations so that you end up with additive inverse coefficients on one of the variables.
The last problem is just realizing that the perimeter is 2L + 2W = 52, and that you are given that L = 2W + 2. Substitute this expression for L in the perimeter equation and solve for W.
