If rx – st = r, which expression represents r.

statuscvo [17]

Answer:

${ \tt{rx - st = r}}$

» Collect like terms, r terms on the left hand side by subtracting r from both sides and adding st to both sides

${ \tt{(rx - st) { \green{ - r + st }} = r{ \green{ - r + st}}}} \\ { \tt{rx - r = st}}$

» On the left hand side, factorise out r

${ \tt{ \green{r(x - 1)} = st}} \\ \\ { \boxed{ \tt{ \blue{ \: r = \frac{st}{x - 1} }}}}$

What’s -2y+16=10 plz solve 2 step equation

konstantin123 [22]

Answer:

y=3

Step-by-step explanation:

To solve this 2 step equation, we need to get y alone. Lets write out the equation

-2y+16=10

Subtract 16 from both sides

-2y-16+16=10-16

Subtract

-2y=-6

divide both sides by -2

-2y/-2=-6/-2

divide

y=3
