Chapter 2: Q72. (page 74)

Solve each equation for $y$ .
$- 3 x - y + 7 = 0$

Short Answer

Expert verified

The required solution is $y = - 3 x + 7$ .

Step by step solution

– State the concept

An equation solved for y gives an equation where y is the only thing on the left-hand side and the other terms are on the right-hand side.

– List the given data

The given equation is $- 3 x - y + 7 = 0$ .

– Solve for y

$- 3 x - y + 7 = 0$ (Given equation)

$- 3 x - y + 7 + y = 0 + y$ (Add y to both sides)

$- 3 x + 7 = y$ (Simplify)

$y = - 3 x + 7$ (Rearrange)

So, the required solution is $y = - 3 x + 7$ .
