Answer:

x=-5

Step-by-step explanation:

4(x-5)+2=x+3 As the first step says, distribute the 4 (multiply all numbers in the parentheses by 4).

4x-20+2=x-3 Combine like terms. For example, the -20 and 2 are like terms because they are both their own numbers and not attached to a variable.

4x-18=x-3 Subtract x from each side. Now, we can get x to only one side.

-x -x

3x-18=-3 Add 18 to both sides.

+18 +18

3x=-15 Divide both sides by 3.

/3 /3

x=-5

I hope this helped you!! Have a great day c:

If f(2x–1) = x+2, then what is the value of f⁻¹(2x–1)?

Anit [1.1K]

Answer:

So F(x+3) = (x+3+5)/2 = (x+8)/2

Step-by-step explanation:

Given F(2x-1) = x+2

Put 2x-1 = y=> x = (y+1)/2

Hence F(y) = (y+1)/2 +2 = (y+5)/2

So F(x) = (x+5)/2

So F(x+3) = (x+3+5)/2 = (x+8)/2.
