Answer:
f = [tex]\frac{7}{15}[/tex]
Step-by-step explanation:
1. 4(4f - 9) = -(2-f) distribute the negative
2. 4(4f - 9) = -2 + f Distribute the 4
3. 16f - 9 = -2 + f Subtract f on both sides
4. 15f - 9 = -2 Add 9 on both sides
5. 15f = 7 Divide both equations by 15
6. [tex]\frac{15f}{15} = \frac{7}{15}[/tex]
f = [tex]\frac{7}{15}[/tex]
