okay it simple as it's just collect the x's terms and nubers term
OpenStudy (anonymous):
and then take the divison
OpenStudy (anonymous):
of operand of x
OpenStudy (anonymous):
so the first step is (5x+4x+11x)+(8+7)=55, right?
OpenStudy (anonymous):
yeah

OpenStudy (anonymous):
then it's obviously 20x+15=55
OpenStudy (anonymous):
then subtract 15 from both sides?
OpenStudy (anonymous):
yes
OpenStudy (anonymous):
no eaxtly
OpenStudy (anonymous):
so it cancels out the 15 on one side and the other side is =40?

OpenStudy (anonymous):
u just move it out 15 to other side
OpenStudy (anonymous):
yes
OpenStudy (anonymous):
finally divide the operand of x
OpenStudy (anonymous):
ok then divided by 20 so it's x=2 ?
OpenStudy (anonymous):
yes
