Substitute x by five
-5+4=-1
4.6y-y+4=y-1.2
We simplify the equation to the form, which is simple to understand
4.6y-y+4=y-1.2
We move all terms containing y to the left and all other terms to the right.
+4.6y-1y-1y=-1.2-4
We simplify left and right side of the equation.
+2.6y=-5.2
We divide both sides of the equation by 2.6 to get y.
y=-2
Answer:
$9.20
Step-by-step explanation:
the tax would be $0.80 because 8% of $10 is $0.80
so the total cost is $10.80

so she will be given $9.20 back in change
