Answer: x = 9

Step-by-step explanation: To solve for <em>x</em> in this equation, we want to get <em>x </em>by itself on the left side of the equation.

Since <em>x</em> is being multiplied by 7, to get <em>x</em> by itself, we need to divide by 7 on the left side of the equation. Since we divided by 7 on the left side, we must also divide by 7 on the right side. On the left side, notice that the 7's cancel out so we're simply left with <em>x</em>. On the right side we have 63 divided by 7 which is 9 so we have <em>x = 9</em>.

Finally, remember to check your answer by substituting a 9 back into the original equation. So we have 7(9) = 63 which is a true statement.

So our answer, x = 9, is correct.

❖ Bob ISN'T correct. 5h^2 has an exponent of 2 while 5h only has an exponent of 1. 5h^2 and 5h are completely different due to the exponent.
