Evaluate f(x)=7(x-1)+8

$f (x) = 7 (x - 1) + 8$

Step 1

Simplify $7 (x - 1) + 8$ .

Simplify each term.

Apply the distributive property.

$f (x) = 7 x + 7 \cdot - 1 + 8$

Multiply $7$ by $- 1$ .

$f (x) = 7 x - 7 + 8$

$f (x) = 7 x - 7 + 8$

Add $- 7$ and $8$ .

$f (x) = 7 x + 1$

$f (x) = 7 x + 1$

Step 2

Subtract $f (x)$ from both sides of the equation.

$0 = 7 x + 1 - f (x)$

Step 3

Rewrite the equation as $7 x + 1 - f (x) = 0$ .

$7 x + 1 - f (x) = 0$
