It is 8x because you're adding them not multiplying them. If you were multiplying it would be8x^2

(f + g)(x) = 2x + 7 + 6x – 5

// 2x + 6x = 8x
// 7 - 5 = 2

Therefore,
(f + g)(x) = 8x + 2

Answer: 8x + 2

Rearrange the equation so uuu is the independent variable. -12u+13=8w-3

Sunny_sXe [5.5K]

Step-by-step explanation:

$- 12u + 13 = 8w - 3 \\ - 12u + 13 + 3 = 8w \\ - 12u + 16 = 8w \\ w = \frac{ - 12u + 16}{8} \\ w = \frac{ - 3}{2} u + 2$

I hope that is useful for you :)
