Question

I have to do a check to make sure this is right. When I turned it in she told me my check was wrong. Please show me how to check my answer. Then I have to substitute my answer into the original equation.3b-2=7b+4
This is how I done my problem.
Subtract 3b from both sides
-2=4b + 4
Subtract 4 from both sides
-6=4b
Divide both sides by 2
-6 divided by 2= -3
4 divided by 2 = 2
Answer: b=-3/2

Answer 1

ur solution is exaclty rite :)

Answer 2

just plug -3/2 everywhere use see b in the equation

Answer 3

but how do I check it. She wants me to write it out.

Answer 4

check it like this:
lhs:3(-3/2)-2=-13/2
rhs:7(-3/2)+4=-13/2 so both sides are equal and hence verified.

Answer 5

got it becca ?
