How do you solve \frac { x } { 10} + 4= 3?

Jun 4, 2018

$x = - 10$

Explanation:

Subtract $4$ from both sides

$\frac{x}{10} + 4 - 4 = 3 - 4$

and then you are left with

$\frac{x}{10} = - 1$

Multiply both sides to cancel the $10$ in the denominator

$10 \cdot \frac{x}{10} = - 1 \cdot 10$

and then you are left with

$x = - 1 \cdot 10$

Simplify it and you are left with

$x = - 10$
