What are the answers to these equations
8=4x-6x
6+2x-6x
-21-2b=-3(2b-1)

8=4x-6x

8= -2x

8/-2= -2x/-2

X=-4

First step:Combine like terms so subtract 4x-6x= -2x so you will get 8=-2x
Note: You combine it because there both x and there in the same equal sign position.

Second step: Get x by it self by dividing -2 on each side as shown above.You divide it because you do the opposite of multiplying.

Answer x=-4

Sorry Idk where the equal sign is I am skipping the second problem.

-21-2b= -3(2b-1)

-21-2b= -6b+3
+2b +2b

-21= -4b+3
-3 -3

-24= -4b

-24/-4= -4b/-4
6=b or b=6

I hope I helped sorry I didn't explain this problem step by step like the 1 st one.

a - base

b - exponent

so,

the base is 8the exponent is 3the exponent tells you to multiply 8 together three timesthe expanded form is 8*8*8

Were is the diagram?
