3|x + 7| = 12

3x+21 = 12

3x = -9

x = -3

-3(x+7) = 12

-3x-21 = 12

-3x = 33

-x = 11

x = -11

3x+21 = 12

3x = -9

x = -3

-3(x+7) = 12

-3x-21 = 12

-3x = 33

-x = 11

x = -11

(1.08×10 3)×(9.3×10 3)÷0.1

(10.8-3) × (93-3) ÷ 0.1

7.8 × 90 ÷ 0.1 = 7.8 × 900 = 7020

(10.8-3) × (93-3) ÷ 0.1

7.8 × 90 ÷ 0.1 = 7.8 × 900 = 7020
