Answer:
$11.50
Step-by-step explanation:
For a system of two variables and two equations, each equation will be a linear graph, and where the lines intersect is the solution as an ordered pair (x,y). If the lines don’t intersect (they’re parallel) so there is no unique solution.
X=5 and Y = 8
Because 5 times 8 equals 40 and -6 times 5 equals -30 so 40-30 equals 10 and 10-10 equals 0
