5b-6+14(5b-6)+2=14+2
Ronch [10]

Answer:

b = 104/75 = 1 29/75 = 1.386666667

Step-by-step explanation:

5b−6+14(5b−6)+2=14+2

Use the distributive property to multiply 14 by 5b−6.

5b−6+70b−84+2=14+2

Combine 5b and 70b to get 75b.

75b−6−84+2=14+2

Subtract 84 from −6 to get −90.

75b−90+2=14+2

Add −90 and 2 to get −88.

75b−88=14+2

Add 14 and 2 to get 16.

75b−88=16

Add 88 to both sides.

75b=16+88

Add 16 and 88 to get 104.

75b=104

Divide both sides by 75.

b=104/75
