I feel as if there is information missing from the question though such as quantities.
421875 cm because you take the 75 and square it to the 3rd power
<span>6(x + 2) - x = 4(x + 4) + 7
Use distributive property
6x+12-x=4x+16+7
Subtract x from 6x
5x+12=4x+16+7
Add 7 to 16
5x+12=4x+23
Subtract 4x from both sides
x+12=23
Subtract 12 from both sides
Final Answer: x=11</span>
