The value at x=2 is 15.

Step-by-step explanation:

Given : Expression 3(x+2)+5x-73(x+2)+5x−7

To find : Simplify the expressions and find the value of x is equal to 2 ?

Solution :

Writ the expression as,

f(x)=3(x+2)+5x-7f(x)=3(x+2)+5x−7

Solve,

f(x)=3x+6+5x-7f(x)=3x+6+5x−7

f(x)=8x-1f(x)=8x−1

Substitute the value of x=2,

f(2)=8(2)-1f(2)=8(2)−1

f(2)=16-1f(2)=16−1

f(2)=15f(2)=15
