Question

solve 2x+3y=12 for x

i don't get this one and i am having a hard time solving equations like these. Help? Thank you!

Answer 1

2x+3y = 12
2x = 12-3y
x = (12-3y)/2

Answer 2

keep the term you are solving for on one side:
2x+3y=12
2x = 12 - 3y
divide both sides by 2 to get x alone

2x/2 = (12-3y)/2

x = (12 - 3y)/2 or 6 - 3y/2 or 6 - 1/5y , which ever way you want it.

Answer 3

Thank u!
