If you're looking for the solution to the system of equations, here's how we solve using substitution
We know that y = x - 1, so we can plug that into the first equation giving
2x - 3(x-1) = -1
Now distribute the 3 giving 2x - 3x + 3 = -1. After combining like terms we get -x + 3 = -1. Now subtract 3 from both sides, -x = -4, and multiply both sides by -1 to make x positive. x = 4
Now we can plug that into the second equation to get y
y = x - 1, and we know that x = 4, so y = 4 - 1, y = 3. The solution is (4, 3)
I think it slopeeeeeeeeeeeeeeeeeeee
4. -8
5. 24
6. I can't see it properly so if it's ÷ answer is 9 if it's - answer is -70
4.00 ÷ 0.25 = 16
.70 ÷ 0.05 = 14
16 quarters + 14 nickels = 30 coins
