Question

if (\frac{1}{3}x + 3 = 6), what is the value of (7x)?
a 147
b 273
c 315
d 441

Explanation:

Step1: Solve for x

First, isolate x in the equation $\frac{1}{7}x + 3=6$. Subtract 3 from both sides: $\frac{1}{7}x=6 - 3$, so $\frac{1}{7}x = 3$. Then multiply both sides by 7 to get $x = 21$.

Step2: Find the value of 7x

Substitute $x = 21$ into $7x$. Then $7x=7\times21 = 147$.

Answer:

A. 147
