Question

inequacao de primeiro grau : 8.(x+3)>12.(1-x)

Answer 1

$8\cdot \left(x+3 \right )>12\cdot \left(1-x \right )\\ \\ 8x+24>12-12x\\ \\ 8x+12x>12-24\\ \\ 20x>-12\\ \\ x>\dfrac{-12}{20}\\ \\ x>\dfrac{-12 \div 4}{20 \div 4}\\ \\ x>-\dfrac{3}{5}$

Answer 2

8(x + 3) > 12(1 - x)

8x + 24 > 12 - 12x

8x + 12x > 12 - 24

20x > - 12

x > - 12/20(÷4)

x> - 3/5
