Question

5.5 = 7.9-0.4x X= Need fast

Answer 1

Answer:

$\boxed {x = 6}$

Step-by-step explanation:

Solve for the value of $x$:

$5.5 = 7.9 - 0.4x$

-Switch sides:

$7.9 - 0.4x = 5.5$

-Subtract both sides by $7.9$:

$7.9 - 7.9 - 0.4x = 5.5 - 7.9$

$-0.4x = -2.4$

-Divide both sides by $-0.4$:

$\frac{-0.4x}{-0.4} = \frac{-2.4}{-0.4}$

$\boxed {x = 6}$

Therefore, the value of $x$ is $6$.
