When solving two-step equations, use inverse operations to undo addition or subtraction first then multiplication or division
OpenStudy (anonymous):
so undo -4 by adding 4 to both sides
OpenStudy (anonymous):
ok now what
OpenStudy (anonymous):
7/8 p = 14
OpenStudy (anonymous):
you want to isolate y by getting one as the coefficient so one option is to multiply 7/8 byt the reciprocal--both sides

7/8 * 8/7 = 1 so 1p or p = 14(8/7)
OpenStudy (anonymous):
p = 14/1 * 8/7
OpenStudy (anonymous):
ok thank you
OpenStudy (anonymous):
p=16
OpenStudy (anonymous):
p=16

plug p=16 into original equation to check
7/8 (16) -4=10
OpenStudy (anonymous):
14-4=10
10=10 YES!

+ 3 first
OpenStudy (anonymous):
no way me to
OpenStudy (anonymous):
do you want to learn the steps
OpenStudy (anonymous):
sure
OpenStudy (anonymous):
g/-5 = -16 (subtract 3 to undo + 3)

ok
OpenStudy (anonymous):
coefficient of g is -1/5 so what is the repriocal(flip numerator and denominator)
OpenStudy (anonymous):
-5/1 so multiply -16 by -5 (-5/1)
g = 80
