4x + 5 = 3x + 84x-3x + 5 - 5 = 3x - 3x + 8 -5x = 3

Both equations are equal and so: 3x+1 = 2x+3 3x-2x = 3-1 x = 2 and by substituting y = 7

x = 0

First of all, if 'x' is 3, then 'x' doesn't equal -3x+3 . You must mean y = -3x + 3.If x=3, then (-3x + 3) = -6 .The graph is the point (3, -6) .

x works out as 5/3

3x + 7 = -3x 6x = -7 x = -7/6

my head hurts now u bich

if 3x+7 = 3 then 3x = 3-7 3x = -4 then, x = -4/3

10 -3x+8x = 25 -3x+8x = 25-10 5x = 15 x = 3

3x + 5 = 20Subtract 5 from each side:3x = 15Divide each side by 3:x = 5

x2 plus 3x plus 3 is equals to 0 can be solved by getting the roots.
