3+p/2=6 How do I solve this?

Diano4ka-milaya [45]

$\boxed{\underline{\bf \: ANSWER}}$

$\sf\frac { 3 + p } { 2 } = 6 \\$

Multiply both sides by 2.

$\sf \: 3+p=6\times 2$

Multiply 6 and 2 to get 12.

$\sf \: 3+p=12$

Subtract 3 from both sides.

$\sf \: p=12-3$

Subtract 3 from 12 to get 9.

$\boxed{\bf \: p=9}$

3x-6y=6 in function notation

JulijaS [17]

Subtract 3x from both sides:

-6y = -3x + 6

divide both sides by -6 to get y by itself:

y = 1/2x - 1

function notation is rewriting y as a function:

f(x) = 1/2x -1
