@wendi20 can you show me your own problem solving again
OpenStudy (anonymous):
answer was 30
OpenStudy (anonymous):
you meant z=3
not z=30
OpenStudy (anonymous):
0.7z+1.9+0.1z=5.5-0.4z
0.8z+1.9=5.5-0.4z
0.8z+0.4z+1.9=5.5
.12z=5.5-1.9
.12z=3.6
then div 3.6/.12
OpenStudy (anonymous):
we didnt move decimals right

yes so its \[\frac{ 3.6 }{ 1.2 }\]
OpenStudy (anonymous):

once taken out to there signs change like neg and pos?
OpenStudy (anonymous):
DISTRIBUTIVE FIRST
OpenStudy (anonymous):
meaning sending the 5y over to the other side and it would then be a neg 5y
OpenStudy (anonymous):
Nope xD
meaning sending the 1/8 over to the parenthesis and do the same thing to the other side
OpenStudy (anonymous):
-1/4(5y+64)=-1/8(20+2y)

or (5y+64)=-1/8+1/4(20+2y)
OpenStudy (anonymous):
No again..
\[\frac{ 1 }{ 8 }(5y+64)=\frac{ 1 }{ 4 }(20+2y)\]
