I wanna say x=3 because 8 times 3 is 24 times 3 is 72 + 8 is 80
412 * 3.75 = 1545, The answer is 1545 miles
The first one is 2x+y=-1
the second one is 13x+2y-1=0
Hi there!

Begin by distributing the 5:
5(2x) + 5(-12) = -90
Simplify:
10x - 60 = -90
Add 60 to both sides:
10x = -90 + 60
10x = -30
Divide both sides by 10:
x = -3
Add 6 to both sides
Solution: k = -30
