Solve the equation for x.
- 7(x + 4) - 4= - 32
Integer or fraction

x=0

Step-by-step explanation:

- 7(x + 4) - 4= - 32

Add 4 to each side

- 7(x + 4) - 4+4= - 32+4

- 7(x + 4) = - 28

Divide by -7

- 7(x + 4) /-7= - 28/-7

x+4 = 4

Subtract 4 from each side

x+4-4 = 4-4

x=0

Hi,

We just need to add the expressions of these 2 functions:

(h + g)(x) = h(x) + g(x) = 3x + 3 -- 4x + 1 = 4 -- x, so (h + g)(x) = 4 -- x.

(h + g)(10) = 4 -- 10 = --6, therefore (h + g)(10) = --6.

Have you understood ?
