(7x + 4) = (3x + 7) Subtract (3x + 4) from both sides of the equation. (7x + 4) - 3x - 4 = (3x + 7) - 3x - 4 4x = 3 x = 3/4 Check: (7x + 4) = 7 (3/4) + 4 = (21/4) + 4 = (21/4) + (16/4) = 37/4 (3x + 7) = 3 (3/4) + 7 = (9/4) + 7 = (9/4) + (28/4) = 37/4 Yay.
if 3x+5=x+19 then x=7
x = 7 and 2/3
(5, 1)
3x+7=19 3x=12 minus 7 from both sides x=4 divide by three on both sides leaving just what x equals
Ten. That means 3x equals 30, and 30 divided by three is ten.
4x plus 7 plus 3x equals 19 plus xx = 2
3x+7=4x 7=4x-3x 7=x
3x + 2y = 7
In the equation 3x plus 7 equals 13, x is equal to 2.
if 3x+7 = 3 then 3x = 3-7 3x = -4 then, x = -4/3
3x + 7 = -4x + 28 implies 7x + 7 = 28
If: 3x+7 = -14 Then: x = -7
(7x + 4) = (3x + 7) Subtract (3x + 4) from both sides of the equation. (7x + 4) - 3x - 4 = (3x + 7) - 3x - 4 4x = 3 x = 3/4 Check: (7x + 4) = 7 (3/4) + 4 = (21/4) + 4 = (21/4) + (16/4) = 37/4 (3x + 7) = 3 (3/4) + 7 = (9/4) + 7 = (9/4) + (28/4) = 37/4 Yay.
3x - 8 = 7 so x = 5
3x-2y-7=0
If: 3x-7+x = 5 Then: x = 3
