Solve for x.

\[\frac{1}{7}(x + 21) = -6\]

(1/7) Multiplied By x is 1/7x And (1/7) Multplied By Positive 21 is 3. So It Will Then Change To 1/7x + 3 = -6. Subtract 3 From Both Sides. Then The Equation Changes To 1/7x = -9 Then Since (1/7) Basically Means To Divide You Would Multiply By 7 On Both Sides And Then x Would Equal -63!(: Then Can Plug In -63 Where x Is To Check Your Work! Hope I Helped!

To solve the equation 7 1 ​ ( x + 21 ) = − 6 , we first distribute, then isolate x by subtracting 3 and multiplying by 7, resulting in x = − 63 . We verified this solution by substituting it back into the original equation. The values match, confirming our answer is correct.
