**math**

you have to solve for x in both problems. in the first problem you have to find common denominators before adding them together. then add them together and solve for x. x=2.4 in the second problem you have to find out what x is less than. add four to both sides then divide by...

**college algebra**

you have to solve for x. -3(x+5)+3 distribute. you'll get... -3x-15+3=12 combine like terms. -3x-12=12 solve for x. add 12 to both sides. -3x=24 divide both sides by -3 x=-8 plug the-8 back in to x to see if your answer is right. -3(x+5)+3=12 -3(-8+5)+3=? -3(-3)+3=? 9+3=? ...
