5x+7=3x-21 -7= -7 5x=3x-14 -3x=-3x 2x=-14 2x/2x=2x/-14 x=-7 The Answer Is -7 -
if 3x+7 = 3 then 3x = 3-7 3x = -4 then, x = -4/3
= 53 9x3 + 9x2 + 5x1+ 3x1 27 + 18 + 5 + 3
7.05 = 7 5/100 = 7 5x1/5x20 = 7 1/20
3x - 7 = 2 3x = 9 x = 3
5x1 = 55x1 = 55x1 = 55x1 = 5
If that's +42x + 49, the answer is (3x + 7)(3x + 7) or (3x + 7)2 If that's -42x + 49, the answer is (3x - 7)(3x - 7) or (3x - 7)2

5x+7=3x-21 -7= -7 5x=3x-14 -3x=-3x 2x=-14 2x/2x=2x/-14 x=-7 The Answer Is -7 -
3x = 7-4x 3x+4x = 7 7x = 7 x = 1
if 3x+7 = 3 then 3x = 3-7 3x = -4 then, x = -4/3
= 53 9x3 + 9x2 + 5x1+ 3x1 27 + 18 + 5 + 3
7.05 = 7 5/100 = 7 5x1/5x20 = 7 1/20
3*4*2 = 12*2 = 24
3x + 4= 7 3x= 7-4 3x/3 = 3/3 x=1
eq: 3x+5=7 =3x=7-5 =3x=2 =x=2/3
