Andrews [41]

3x = 2x + 7<br> 4 5<br> x = ?

<h2>Solve for <em>x</em> | Solution and Explanation</h2>

_______________________________________________

We are given the following expression:

$\frac{3x}{4} =\frac{2x+7}{5}$

1. Apply fraction cross multiply (if $\frac{a}{b}=\frac{c}{d}$ , then $a$ × $d$ = $b$ × $c$ )

$3x$ × $5 = 4(2x+7)$

==================

2. Simplify.

$15x=4(2x+7)$

==================

3. Expand 4(2x + 7).

$15x=8x+28$

===========================

4. Subtract 8x from both sides.

$15x-8x=8x+28-8x$

=======================

5. Simplify.

$7x=28$

=======================

6. Divide both sides by 7.

$\frac{7x}{7}=\frac{28}{7}$

========================

7. Simplify.

$x=4$

=========================

Hope this helps!
