Question

Solve the equation for x. x/3 = (2x + 3)/7

Answer 1

Answer:

Our answer is $x=9$

Step-by-step explanation:

First we will rearrange so we have to divide by 7.

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

Now we will cross multiply.

So...

$x*7 \\3*2x+3$

Our new equation will look like:

$7x=6x+9$

Now we have to isolate x.

So we have to subtract 6x from both sides.

$7x-6=1x$

and

$6x-6x=0$

Our new equation is:

$1x=9$

Now divide.

Our answer is $x=9$

Hope this helped!

Answer 2

X = 3

First u cross multiply

7x =3(2x +3)
Multiply parentheses by 3


7x = 6x =9
Move variable to the left

7x - 6x =9
Collect the terms

x = 9
