Answer:
4/15
Step-by-step explanation:
2x/5-3y/2=7
<em>Multiply all terms by the lcd.</em>
10(2x/5) + 10(-3y/2) = 10(7)
<em>Cross cancel.</em>
2(2x)+ 5(-3y) =70
<em>Simplify.</em>
4x -15y = 70
<em>Subtract 4x from both sides.</em>
-15y = -4x +70
<em>Divide by -15 on both sides.</em>
y= 4/15x -24/3
<span>9c+(8+3c)
9c+8+3c (collect like terms)
9c+3c+8
12c+8
12c+8 is the answer.
im not sure if your teacher also wants the answer to be in simplest form so im going to do that below as well:
12c+8 (4*3=12 and 4*2=8. you can take out a 4 from those 2 numbers)
4(3c+2) (this is the simplest form of </span>9c+(8+3c)<span>)
