➤ [ Step One ] Multiply Both Sides By 10

`\bold{3.2b\cdot \:10-4.7\cdot \:10=3b\cdot \:10-3.3\cdot \:10}`

➤ [ Step Two ] Refine

`\bold{32b-47=30b-33}`

➤ [ Step Three ] Subtract 30b From Both Sides

`\bold{32b-30b=30b+14-30b}`

➤ [ Step Four ] Simplify

`\bold{2b=14}`

➤ [ Step Five ] Divide Both Sides By 2

`\bold{(2b)/(2)=(14)/(2)}`

➤ [ Step Six ] Simplify

`\bold{b=7}`

Answer 2

Add 4.7 to both sides

3.2b = 3b - 3.3 + 4.7

Simplify 3b - 3.3 + 4.7 to 3b + 1.4

3.2b = 3b + 1.4

Subtract 3b from both sides

3.2b - 3b = 1.4

Simplify 3.2b - 3b to 0.2b

0.2b = 1.4

Divide both sides by 0.2

b = 1.4/0.2

Simplify 1.4/0.2 to 7

b = 7
