Solve for F.<br> 3(6-f)-4=3f-4
Alinara [238K]

Answer:

F=3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3(6−f)−4=3f−4

(3)(6)+(3)(−f)+−4=3f+−4(Distribute)

18+−3f+−4=3f+−4

(−3f)+(18+−4)=3f−4(Combine Like Terms)

−3f+14=3f−4

−3f+14=3f−4

Step 2: Subtract 3f from both sides.

−3f+14−3f=3f−4−3f

−6f+14=−4

Step 3: Subtract 14 from both sides.

−6f+14−14=−4−14

−6f=−18

Step 4: Divide both sides by -6.

−6f−6=−18−6f=3

Answer:

f=3
