Simplify each expression and evaluate it for x=3, 3(2x+6)−(3x+1) The simplified expression is : The value of the expression for the given x is :
Given the expression;
3(2x+6) - (3x-1)
On simplification:
= 3(2x) + 3(6) -3x + 1
= 6x + 18 - 3x + 1
= 6x - 3x + 18-1
= 3x + 17
If x = 3
f(3) = 3(3) + 17
f(3) = 9 + 17
f(3) = 26
