Solve each equation and check your solution <br> -3w-4=w+3

denpristay [2]

Answer:

$\boxed {w = - \frac{7}{4} }$

Step-by-step explanation:

We want to solve the linear equation -3w-4=w+3

We group like terms to get

$- 3w - w = 3 + 4$

$- 4w = 7$

Divide both sides by -4

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

Now let us check

$- 3 \times - \frac{7}{4} - 4 = - \frac{7}{4} + 3$

$\frac{21}{4} - \frac{16}{4} = - \frac{7}{4} + \frac{12}{4}$

$\frac{5}{4} = \frac{5}{4}$

This is true
