To answer this question, we need to first know what f(x) means. For example, if f(10), then you plug in 10 for x, 7(10)+2 = 72.
Do the same thing but with f(7).
f(7) = 7(7)+2
f(7) = 49+2
f(7) = 51
Hope this helps.

Solve the linear equation.
Nataliya [291]

7x+10=\dfrac{1}{3}(12x-3)+14x\qquad\text{use distributive property}\\\\7x+10=\dfrac{1}{3}\cdot12x-\dfrac{1}{3}\cdot3+14x\\\\7x+10=4x-1+14x\\\\7x+10=18x-1\qquad\text{substitute 10 from both sides}\\\\7x=18x-11\qquad\text{subtract 18x from both sides}\\\\-11x=-11\qquad\text{divide both sides by (-11)}\\\\\boxed{x=1}
