5x - 47< 3(12x - 108) – 2

TEA [102]

Answer:

9 < x

Step-by-step explanation:

5x - 47< 3(12x - 108) – 2

Distribute

5x - 47< 36x - 324 – 2

Combine like terms

5x - 47< 36x-326

Subtract 5x from each side

5x-5x - 47< 36x-5x-326

- 47< 31x-326

Add 326 to each side

326 - 47< 31x-326+326

279 < 31x

Divide by 31 on each side

279/31 < 31x/31

9 < x

Kitty [74]

Answer:

4 years

Step-by-step explanation:
