Multiple Choice

Use the following equation to isolate the variable "x".

$$x+z=y$$  

• $$x=y-z$$  

• $$x=y+z$$  

• $$x=yz$$  

• $$x=z-y$$  

Multiple Choice

Use the following equation to isolate the variable "z".

$$ax+z=by$$

• $$z=ax-by$$  

• $$z=by-ax$$  

• $$z=by+ax$$  

• $$z=axby$$  

Multiple Choice

Use the following equation to isolate the variable "m".

$$\frac{m}{p}=k$$

• $$m=k-p$$  

• $$m=kp$$  

• $$m=k+p$$  

• $$m=\frac{k}{p}$$  

Multiple Choice

Use the following equation to isolate the variable "y".

$$a+b=xy$$

• $$y=\frac{a+b}{x}$$  

• $$y=x\left(a+b\right)$$

• $$y=a+\frac{b}{x}$$  

• $$y=\frac{a}{x}+b$$  

Multiple Choice

Use the following equation to isolate the variable "a".

$$a+b=xy$$

• $$a=xy+b$$  

• $$a=xy-b$$

• $$a=\frac{xy}{b}$$  

• $$a=\frac{x+y}{b}$$
