Hey there!


CURRENT EQUATION:
x/3 + 7 = -5


CONVERT:

1/3x + 7 = -5


SUBTRACT 7 to BOTH SIDES:

1/3x + 7 - 7 = -5 - 7

CANCEL out: 7 - 7 because it give you 0

KEEP: -5 - 7 because it help solve for the x-value


NEW EQUATION: 1/3x = -5 - 7


SIMPLIFY IT!

1/3x = -12


MULTIPLY 3/1 to BOTH SIDES: (3/1 = 3)

3 * 1/3x = -12 * 3

CANCEL out: 3 * 1/3 because it give you 1

KEEP: -12 * 3 because it help give you 1


NEW EQUATION: x = -12 * 3


SIMPLIFY IT!

x = -36

Therefore, your answer is: x = -36



Good luck on your assignment & enjoy your day!

Explanation:

Simplify.

Subtract 7 from both sides:


(x)/(3) =-12

Multiply each side by 3 to remove the fraction:


\boxed{x=-36}
