We must solve: 1.2r = -1 + 28

Step one: combine like terms by adding together -1 and 28:

1.2r = 27

Step two: divide both sides by 1.2 ino order to solve for r:

1.2r/1.2 = 27/1.2

Step three: notice that we can cancel out 1.2 on the lefthand side:

r = 27/1.2

Step four: divide 27 by 1.2, bringing us to our final solution:

**r = 22.5**

1.2r =-1+28

combine like terms

1.2r = 27

divide by 1.2:

r= `27/1.2`

r = 22.5

1.2r=-1+28

combine like terms (-1 and 28)

1.2r = 27

divide by 1.2 because we want r to be alone:

r= 27/1.2

r = 22.5

To solve:

- Rewrite: 1.2r=28+(-1)
- Simplify: 1.2r=27
- What is the opposite operation of multiplication? (division) -- Divide 1.2 from both sides to isolate r: `(1.2r)/(1.2)=27/1.2`
- Simplify r=22.5
- ` `

1.2r = -1 + 28

To solve this equation , combine both like terms ( which is -1 and 28 )

By combining like terms , you should get

1.2r = -27 now divide both sides by 1.2

By dividing both sides by 1.2r , you should get

r = 22.5 which is your answer
