Answer:
m=-29/3 and n=65/3
Step-by-step explanation:
The given system has equations:
3m+3n=36
8m+5n=31
Multiply the top equation by 5 and bottom equation by 3 to get:
15m+15n=180
24m+15n=93
Subtract the top equation from the bottom equation to get:
9m=-87
Divide both sides by 9
We substitute this value into the first equation to get:
0.43 should be the answer.
The expression that could best describe the statement would be " 40 n + 20
260.
<span>9x-7=-7
You would add 7 to both sides because you want to get to the point were your variable is alone. 9x = 0 Then you would dicide each side by 9 because after doing this your variable would be alone. x = 0 would be your final answer.

Solution
1) Simplify
<span> to </span>
<span>−2= </span>
+
2) Simplify
+
<span>to <span>914</span>
</span>
<span>−2= </span>
3) <span>Add 2 to both sides
</span>
=
<span>+2
</span>
4) Simplify
<span><span>+2</span> to </span>
=
5) <span>Multiply both sides by 7
</span><span>4y= </span>
<span>×7
</span>
6) Simplify
<span><span>×7</span> to </span>
=
7) Simplify
<span> to </span>
=
8) <span>Divide both sides by 4
</span>y=
<span>×4
</span>
9) <span>Simplify <span>2×4</span> to 8
</span><span>y=</span>
<span><span>
