Question

me ajudem a resolver essas equações! Por favor

Answer 1

8(x-1)=8-4(2x-3)   8x-8=8-8x+12   8x+8x=8+12+8   16x=28   x=28/16   x=7/4

x/2-x/4=5    2x-x/4 = 20/4    2x - x=20   x=20

x/5+ 1 = 2x/3    3x + 15/15 = 10x/15    3x - 10x = -15   -7x=-15 .(-1)  7x=15  x=15/7

x/2-x/4=1/2   2x-x/4 = 2/4   2x-x=2     x=2

x/5 + x/2 = 7/10    2x+5x/10 = 7/10      2x+5x=7     7x=7  x=7/7     x=1

x/2+x/3=1    3x+2x/6=6/6   3x+2x=6    5x=6      x=6/5
