# How do you solve for x in y=7mx+4b?

Mar 25, 2018

$x = - \frac{4}{7}$

#### Explanation:

$\text{The formula of a linear equation is}$ $\textcolor{v i o \le t}{y = m x + b}$

$\text{To solve for x you make y=0}$

$y = 7 x + 4$

$0 - 4 = 7 x$

$- 4 = 7 x$

$x = - \frac{4}{7}$

$\therefore$ $\left(- \frac{4}{7} , 0\right)$
