Answer: x = -7

Step-by-step explanation: To solve for x in this equation, we want to get x by itself on the left side of the equation. Since x is being multiplied by 7, to get x by itself, we need to divide by 7 on the left side of the equation. Since we divide 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 and we're simply left with x. On the right side, we have -49 divided by 7 which is -7 so we have x = -7 which is the solution to our equation.

Finally, remember to check your answer by substituting a -7 back into the original equation so we have 7(-7) = - 49 or -49 = -49 which is a true statement so we know our answer is correct.

Remember to show all your work when solving equations.
