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:

$\frac{8}{7}r+5=-11\Rightarrow\frac{8}{7}r=-16$$\Rightarrow r=-14$

*4th:

$\frac{1}{6}z-3=-1\Rightarrow\frac{1}{6}z=2$$\Rightarrow z=12$
