Exercise Set 11.3
Solve each system of equations. Check your answers.
a. 6a þ 4b ¼ 15
a þ 2b ¼ 12
b. a 4b ¼ 12
7a 6b ¼ 8
c. 6x 12y ¼ 16
3x 4y ¼ 8
Systems with No Solutions
Figure 11.3 illustrates two lines with the same slope. They are parallel to each
other, so they never intersect. The equations as given read this way:
y ¼ x þ
3
y ¼ x

Figure 11.3
Lines that do not intersect have no solution.
