\[\frac{ 2x+1 }{3 }=\frac{ x+6 }{ 2 }\]
Could someone show me step by step how to solve this?
OpenStudy (anonymous):
cross multiply first that gives you
2(2x+1) = 3(x+6)
OpenStudy (anonymous):
now distribute
4x+2 = 3x +18
OpenStudy (anonymous):
are you following...
OpenStudy (anonymous):
Yeah... I'm a bit confused on the cross multiplying

ok lets go back, in order to get rid of the bottom for the left side lets multiply both sides by 3
3(2x+1)/3 = 3(x+6)/2 which reduces to 2x+1 = 3(x+6)/2
OpenStudy (anonymous):
now on the right side we want to get rid of 2 so lets multiply both sides by 2
2*(2x+1) = 2*3*(x+6)/2 but that reduces to 2*(2x+1) = 3*(x+6)
since 3/3 and 2/2 reduces to 1
OpenStudy (anonymous):
cross multiplication is just a quicker way to do it and it always works
OpenStudy (anonymous):
so now we just distribute 2*(2x+1) = 3*(x+6)
and gives 4x + 4 = 3x + 18
OpenStudy (anonymous):
4x + 2 = 3x +18 sorry typo

Okay... So then we just do the regular solving of it?
The whole, take 3x away from both sides, then take 2 away from both sides?
OpenStudy (anonymous):
yes
OpenStudy (anonymous):
So.. x=16?
OpenStudy (anonymous):
yes thats correct
OpenStudy (anonymous):
Awesome! Thank you!
