Question 9131: Desperate Mother trying to check my childs homework problems. I havn't seen Algebra in years. PLease Help!!!!! Thank You


can'tsolve 13+c=-38
w+14=-8
4.2=n+7.3
y+(-10)=6
y-7=8
-13=5+x
19-k=32
x-4=6
-12=7-h
-15=u+(-5)
j-(-17)=36
-10-a=-17
y-(-1.5)=0.5
k +(-4.21)=-19.3
52=41-u
s+(-28)=0
9/10=k+7/10
-7/8-x=-7/12

You can put this solution on YOUR website!
Mom, I think this is too many to solve. I will do the first to and show you and you can continue the rest.
can'tsolve 13+c=-38 = All you want to do is move the number, not the c(called the variable) to the right of the equal sign.
13%2Bc=-13 You would subtract the opposite, so if it is a positive 13, it become a negative 13. To get a variable alone, you must move all the number to the the side of equal sign
c=-26
w%2B14=-8
w=22
4.2=n%2B7.3
-3.1=n
Hopefully this helps you
