Why?
</span></span>Let's solve your equation step-by-step.
<span><span>2<span>(<span>x−7</span>)</span></span>=<span><span>10x</span>+18
</span></span>Simplify both sides of the equation.
<span><span>2<span>(<span>x−7</span>)</span></span>=<span><span>10x</span>+18
</span></span><span>Simplify:
</span><span><span><span>2x</span>−14</span>=<span><span>10x</span>+18
</span></span>Subtract 10x from both sides.
<span><span><span><span>2x</span>−14</span>−<span>10x</span></span>=<span><span><span>10x</span>+18</span>−<span>10x
</span></span></span><span><span><span>−<span>8x</span></span>−14</span>=18
</span>Add 14 to both sides.
<span><span><span><span>−<span>8x</span></span>−14</span>+14</span>=<span>18+14
</span></span><span><span>−<span>8x</span></span>=32
</span>Divide both sides by -8.
<span><span><span>−<span>8x</span></span><span>−8</span></span>=<span>32<span>−8

Step-by-step explanation:
- Plot each point on the graph corextly using (x,y).
- The line should go verticle
- Since x doesnt change, there is no slope / the line will go up and down infinate
Direct variation is
y=kx
subsitute
-6=-36k
diivde both sdies by -36
1/6=k
the equation is
y=1/6x or B
