Answer
No solutions
See graph below.
Work Step by Step
Given the system of equations:
1. $6x - 8y = 15$
2. $-1.5x + 2y = -4$
It asks to find all solutions and to graph.
Multiply equation 2 by 4, then add it to equation one
1. $6x - 8y = 15$
2. $-6x + 8y = -16$
$0 + 0 = -1$
$0 = -1$
Since 0 is not equal to -1, then there are no solutions present. The lines are parallel to each other.
