3x/7 + 5y/14x = 3x*2x/(7*2x) + 5y/14x = (6x2 + 5y)/14x
3x + 2 + 2x = 7; 3x + 2x = 5x, so 5x + 2 = 7; 7-2=5, so 5x=5. 5x divided by 5 and 5 divided by 5 equals 1, so x equals 1.
=3x+7
(-3x - 1)(3x - 7)
Ten. That means 3x equals 30, and 30 divided by three is ten.
38*4 + 3 + 7 - 3x = 162 - 3x
3x - 7 + 4x = 28 7x - 7 = 28 I added 4x and 3x to get 7x 7x = 35 I subtracted 7 from both sides x = 5 I divided by 7 on both sides
3x+7=4x 7=4x-3x 7=x
0.4286
5x+7
13x + 7
if 3x+7 = 3 then 3x = 3-7 3x = -4 then, x = -4/3
