5x-3=12x+11
First subtract 5x from both sides:
-3 = 7x + 11
Subtract 11 from both sides:
-14 = 7x
Divide by 7 on both sides:
x = -2
OpenStudy (anonymous):
oh i was trying to add 5 to both sides
OpenStudy (anonymous):
oh do you get the second one? or do you need explanation?
OpenStudy (anonymous):
do i add -7 to 2(3p+6)
OpenStudy (anonymous):
you multiply: -7(5p) + -7(3) and that gives you an equation as:
-35p + -21-49 = 6p +6

so at the end your equation is -76 =9p and then you get the answer by dividing 9p to -76
OpenStudy (anonymous):
that what i got but i get -8.4 it does not look right
OpenStudy (anonymous):
the third answer is 22 + 11n and i don't know if you want me to simplify it or keep it like this
OpenStudy (anonymous):
hmmm let me try the second answer again...
OpenStudy (anonymous):
