# How do you solve 5= -3+2x?

May 1, 2018

$x = 4$

#### Explanation:

$5 = - 3 + 2 x$

We want to solve for $x$, so we need to make $x$ alone. To do that, first add $\textcolor{b l u e}{3}$ to both sides of the equation:
$5 \quad \textcolor{b l u e}{+ \quad 3} = - 3 + 2 x \quad \textcolor{b l u e}{+ \quad 3}$

$8 = 2 x$

Now divide both sides by $\textcolor{b l u e}{2}$:
$\frac{8}{\textcolor{b l u e}{2}} = \frac{2 x}{\textcolor{b l u e}{2}}$
$4 = x$

So the final answer is
$x = 4$

Hope this helps!

$x = 4$

#### Explanation:

We are given $5 = - 3 + 2 x$

Add +3 to both sides.

$5 + 3 = - 3 + 3 + 2 x$

Swap sides and sum.

$- 3 + 3 + 2 x = 5 + 3$
$\text{ } 0 + 2 x = 8$

Divide both sides by 2.

$\frac{2 x}{2} = \frac{8}{2}$

And simplify.

$x = 4$
