Answer:
x = -21
Step-by-step explanation:
<h2>Words To Algebra:</h2>
Words : Five more than one-third of a number = -2
Algebraic Equation: 5 + (1/3)x = -2
<h2>Isolate x:</h2>
5 + (1/3)x = -2
Subtract 5 from both sides
5 + (1/3)x - 5 = -2 - 5
(1/3)x = -7
Multiply All sides by 3
(1/3)x * 3 = -7 * 3
x = -21
<h2 /><h2>Check:</h2>
5 + (1/3)-21 = -2
5 + -7 = -2
-2 = -2
