solve for x X/5 - 7 = 2q

2. anonymous

I got x=45q

3. marigirl

$\frac{ x }{ 5 } -7= 2q$ Is that the equation

4. anonymous

yup

5. marigirl

$\frac{ x }{ 5 } = 2q+7$ $x= 5(2q+7)$

6. anonymous

that is the x

7. anonymous

how did u get explain in clear way

Its about balancing the equation $\frac{ x }{ 5 } -7= 2q$ First I want to add 7 to each side $\frac{ x }{ 5 }=2q+7$ Since 2q and 7 are not like term we cant add them together. so we just express it like that Next I want to multiply both sides by 5 $x= 5(2q+7)$ Now expand the brackets $x= 10q+35$ again, 10q and 35 are not like terms, hence we dont add them together but leave it as it os.

Look more into adding like terms, what your doing is adding 7 to 2q which we dont do in mathematics. we can only add two terms if they look EXACTLY the same. for example if it was 7q and 2q = 9q but 7 + 2q = 7 + 2q
