Answer:

2)7/8

3)5/6

Step-by-step explanation:

2)

\frac{1}{2}  \times  4 =  \frac{4}{8}

4/8+3/8=7/8

3)

\frac{1}{2}  \times 3 =  \frac{3}{6}

mx=y+7

Divide both sides by m.

m

Help me i think its add 24 to both sides
umka2103 [35]

It is given in the question that

Steven is solving the equation

3(8-2x)+40=34

He begins with the following two steps.

Step 1: 3(8)+3(-2x)+40=34  Step 2: 24-6x+40=34

And we have to find , what will be the next step in solving the equation.

First we combine the like terms. And the like terms are 24 and 40. So we have to add 24 and 40. And that will be the next step.

So the correct option is the last option.
