Question

Solve for the variable in each of the following equations. Write the answer as an equation.

Answer 1

We will determine the value for each variable respectively as follows:

*1st:

`-4t-6=14\Rightarrow-4t=20`
`\Rightarrow t=-5`

*2nd:

`15=-1-2w\Rightarrow-2w=16`
`\Rightarrow w=-8`

*3rd:

`(8)/(7)r+5=-11\Rightarrow(8)/(7)r=-16`
`\Rightarrow r=-14`

*4th:

`(1)/(6)z-3=-1\Rightarrow(1)/(6)z=2`
`\Rightarrow z=12`
