Answer:

x = 10

Step-by-step explanation:

FIrst, you want to use the distrutive properity.

2x + 10 = 30

Now you want to subtract 10 from both sides

2x = 20

Next, you want to divide 2 from both sides.

x = 10

If h(x) = f(x) - g(x) = 2x, at what x-value will f(x) = g(x) + 20?
Olegator [25]

Answer:

B

Step-by-step explanation:

This is a neat question

f(x) - g(x) = 2x           Add g(x) to both sides

f(x) = g(x) + 2x

Now you need the right hand side to have 20 added to g(x).

2x must = 20

2x = 20                    Divide by 2

x = 20/2

x = 10

So the answer must be x = 10
