rozwiąż równania: 1 3/4+2x=-3 1/4 1/2(x+4)=-1/2x+7

3/4+2x=-3/4 2x=-3/4-3/4 2x=-6/4 /2 x=-3/2=-1 1/2

1,75 + 2x=-3,25 2x=-3,25-1,75 2x=4/:2 x=2 0,5(x+4)=-0,5x+7 0,5x+2=0,5x+7 0,5x-0,5x=7-2 0=5

7/4 + 2x = -13/4 / *4 7 + 4x = -13 / -7 4x = - 20 / :4 x = - 5 1/2x + 2 = 1/2x + 7 / *2 x + 4 = x + 7 / -4 x = x - 3 / -x 0 = -3
