13. 3(x-6)-8=-2 (you have to plug in x-6 as x in the equation
3x-18-8=-2 (distribute 3)
3x-26=-2 (combine like terms)
3x=24 (subtract 26 to both sides)
x=8 (divide 3 to both sides)
14. -2(3(5y+5)=-4
-2(15y+5)=-4
-30y-10=-4
30y=6
y=1/5
15. (3x-5) +2x = 90
16. Let m be the number of minutes
0.75m+32 = 47
Using this equation you can find the number of minutes.
0.75m = 15 ( subtract 32 to both sides)
m= 20 (divide 0.75 to both sides)
Vera called 20 minutes beyond her allowed minutes.
Here I hope that this helped you out hon :)
