Write as a Function of b a-7=3(b+2)

$a - 7 = 3 (b + 2)$

Step 1

Simplify $3 (b + 2)$ .

Rewrite.

$a - 7 = 0 + 0 + 3 (b + 2)$

Simplify by adding zeros.

$a - 7 = 3 (b + 2)$

Apply the distributive property.

$a - 7 = 3 b + 3 \cdot 2$

Multiply $3$ by $2$ .

$a - 7 = 3 b + 6$

Step 2

Move all terms not containing $a$ to the right side of the equation.

Add $7$ to both sides of the equation.

$a = 3 b + 6 + 7$

Add $6$ and $7$ .

$a = 3 b + 13$

Step 3

To rewrite as a function of $b$ , write the equation so that $a$ is by itself on one side of the equal sign and an expression involving only $b$ is on the other side.

$f (b) = 3 b + 13$

Write as a Function of b a-7=3(b+2)
