-4(4-x)=4/5(x+16) I need help
Dominik [7]

Answer:

x=9

Step-by-step explanation:

−4(4−x)=4/5(x+16)

(−4)(4)+(−4)(−x)=(4/5)(x)+(4/5)(16)(Distribute)

−16+4x=4/5x+64/5

4x−16=4/5x+64/5

4x−16−4/5x=4/5x+64/5−4/5x

16/5x−16=64/5

16/5x−16+16=64/5+16

16/5x=144/5

(5/16)*(16/5x)=(5/16)*(144/5)

x=9

hopfully this helps answer: x=9
