2/3x - 2 = 7 solve the equation

1 answer:

3 0

Isolate the x.

Do the opposite of PEMDAS. Note the equal sign. What you do to one side, you do to the other.

2/3x - 2 = 7

Add 2 to both sides

2/3x - 2 (+2) = 7 (+2)

2/3x = 9

Multiply 3/2 to both sides to isolate the x

2/3x(3/2) = 9(3/2)

x = 9(3/2)

Multiply 9 with 3, and divide by 2

9 x 3 = 27
27/2 = 13.5

x = 13.5 is your answer

hope this helps

If n+h/5=f+9/9, then n/5=

Ann [662]

------------------------------------------------------------------
Question
------------------------------------------------------------------
$\boxed { \frac{n+h}{5} = \frac{f+9}{9}}$

------------------------------------------------------------------
Split the fraction on the left
------------------------------------------------------------------
$\boxed { \frac{n}{5} + \frac{h}{5} = \frac{f + 9}{9}}$

------------------------------------------------------------------
Take away h/5 from both sides
------------------------------------------------------------------
$\boxed { \frac{n}{5} = \frac{f+9}{9} - \frac{h}{5}}$

------------------------------------------------------------------
Change the denominator to be the same
------------------------------------------------------------------
$\boxed { \frac{n}{5} = \frac{5f+45}{45} - \frac{9h}{45}}$

------------------------------------------------------------------
Put it into single fraction
------------------------------------------------------------------
$\boxed { \frac{n}{5} = \frac{5f+45-9h}{45} }$

-------------------------------------------------------------------
Rearrange (This step may not be necessary)
------------------------------------------------------------------
$\boxed {\frac{n}{5} = \frac{5f-9h+ 45}{45} }$

$\bf \Longrightarrow \ Answer \ : \boxed {\boxed {\frac{n}{5} = \frac{5f-9h+ 45}{45} }}$
