Answer:
heck ya
Step-by-step explanation:
Math:
Step #1: Simplify both sides of the equation.<span><span><span>
14</span>(8x+16)</span>=<span>4<span>x
Step #2: Simplify
</span></span></span><span><span><span>(1/4)(8x)</span>+<span>(1/4)(16)</span></span>=4x</span>(Distribute)
<span>2x+4=<span>4<span>x
</span></span></span>Step 3: Subtract 4x from both sides.
<span><span>2x+4</span>=<span>4x
-4x -4x
</span></span><span><span><span>−2x</span>+4</span>=<span>0
</span></span>Step #3: Subtract 4 from both sides.
<span><span><span><span>−<span>2x</span></span>+4</span></span>=<span>0
-4 -4
Step #4: Divide -2 from both sides.
</span></span><span><span>−<span>2x</span></span>=<span>−<span>4
/-2 /-2
Your Answer:
x = 2
</span></span></span>
