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.

Answer:
8 m = width
28 m = length
Step-by-step explanation:
Let w = width
3w + 4 = length
P = 2w + 2l
= 2w + 2(3w + 4) = 72
2w + 6w + 8 = 72
8w + 8 = 72
8w = 64
w = 8 m = width
3w + 4 = 24 + 4 = 28 m = length
