Answer:
<em>x = 19 </em>
Step-by-step explanation:
First, distribute the 2 on the left side.
2(x - 5) - 8 = 20
2x - 10 - 8 = 20
Combine like terms on the left side.
2x - 18 = 20
Add 18 to both sides.
2x = 38
Divide both sides by 2.
x = 19
Answer:
Solution for 2(x-5)-8=20 equation:
Simplifying
2(x + -5) + -8 = 20
Reorder the terms:
2(-5 + x) + -8 = 20
(-5 * 2 + x * 2) + -8 = 20
(-10 + 2x) + -8 = 20
Reorder the terms:
-10 + -8 + 2x = 20
Combine like terms: -10 + -8 = -18
-18 + 2x = 20
Solving
-18 + 2x = 20
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '18' to each side of the equation.
-18 + 18 + 2x = 20 + 18
Combine like terms: -18 + 18 = 0
0 + 2x = 20 + 18
2x = 20 + 18
Combine like terms: 20 + 18 = 38
2x = 38
Divide each side by '2'.
x = 19
Simplifying
x = 19

(f + g)(x) = 3x^2 + 3x/2 - 9
Step-by-step explanation:
In order to find a composite function through addition, you simply add the two equations together.
f(x) + g(x)
x/2 - 3 + 3x^2 + x - 6
3x^2 + 3x/2 - 9
