Solve the formula A=10+ry. solve for y
noname [10]

The given formula A= 10 + ry

Solve for y means we have to make y alone

A= 10 + ry \\

Add -10 on both sides, we get

A - 10 = 10 -10 + ry \\A - 10 = 0 + ryA - 10 = ry

As there is multiplication sign between r and y so to solve for y, divide both side by r

\frac{A - 10}{r} = y\\\\y = \frac{A - 10}{r}

Create a system of equations
Vika [28.1K]

Answer:

Answer: Janet is 16, and David is 11.

Step-by-step explanation:

Let the ages be j and d.

j = d + 5

j + d = 27

Substitute d + 5 for j in the second equation.

d + 5 + d = 27

2d + 5 = 27

2d = 22

d = 11

Substitute 11 for d in the first equation.

j = d + 5

j = 11 + 5

j = 16

Answer: Janet is 16, and David is 11.
