Question

Consider the equation 3a+0.1n=123 if we solve this equation for n which equation would result.

Answer 1

Answer:

$n = 1230 - 30a$

Step-by-step explanation:

Given

$3a + 0.1n = 123$

Required

Solve for n

$3a + 0.1n = 123$

Subtract 3a from both sides

$3a - 3a + 0.1n = 123 - 3a$

$0.1n = 123 - 3a$

Divide through by 0.1

$n = \frac{123 - 3a}{0.1}$

Split the fraction

$n = \frac{123}{0.1} - \frac{3a}{0.1}$

$n = 1230 - 30a$
