Answer:

4

Explanation:

One:

13y+2-2y=10y+3-y

* first step is to simplify (combine like terms) *

11y+2=9y+3

* Subtract 2 from both sides (you want like terms on the same side) *

11y = 9y + 1

* Subtract 9y from both sides (again you want like terms on the same side) *

2y = 1

* Divide through by 1 *

y = 1/2

Two:

9(3y+7)-2=3(-9y+9)

* Simplify (combine like terms) *

27y+61=-27y+27

* Subtract 27 from both sides*

27y+34=-27y

* Subtract 27y from both sides*

34=-54y

* Divide through by 34 *

y = -17/27

Three:

32.1y+3.1+2.4y-8.2=34.5y-5.1

* Simplify (combine like terms) *

34.5y-5.1=34.5y-5.1

* From here you can see that all real numbers would work *

All real numbers

Four:

5(2.2y+3.4)=5(y-2)+6y

* Simplify (combine like terms) *

11y+17=11y-10

* The 11y s would cancel leaving you with no solution*

No solution
