4x+7-3x = 15 4x-3x = 15-7 x = 8
5+4x-7 = 4x+3-x 4x-2 = 3x+3 4x-3x = 3+2 x = 5
7x = 3x - 12 4x=-12 x=-3
3x+5 = 4x-10 In algebra, what you do to one side you do the other Now you add 10 to both sides 3x+5 + 10 = 4x-10+10 3x +15 = 4x now subtract 3x from both sides 3x-3x +15 = 4x-3x 15 = x
You need to organise your question properly. 3x+2y=4 4x + 3y= 7? Is 4 4x = 44x or 4-4x or 4+4x How can there be 2 equal signs in 1 equation?
4x+7-3x = 15 4x-3x = 15-7 x = 8
5+4x-7 = 4x+3-x 4x-2 = 3x+3 4x-3x = 3+2 x = 5
3x+7=4x-73x=(-)7+4x-4x(-)1x=(-)7________(-)1x=7add (-3x) to each side of equation3x +7 = 4x-3x +3x +7 = 4x -3x0 +7= 1x7=x
The given equation: =3x-4x plus 9xy-12y =3x-4x+9xy-12y =-x+9xy-12y =-x+3y(3y-4) Answer.
5+4x-7=4x+3-1x 4x-2=3x+3 (combined the like terms) +2 +2 (add 2 to both sides) 4x=3x+5 -3x -3x (subtract 3x from both sides) x+5
4x-y2=2xy 2x ? y5 if its plus its 7 xy
7x = 3x - 12 4x=-12 x=-3
3x - 5x + 4x = -2x +4x = 2x
x + 5 = 4x/3 Solve for x multiply both sides of the equation by 3... 3 * (x + 5) = 3 * (4x/3) 3x + 15 = 4x subtract 3x from both sides of the equation (3x + 15) - 3x = (4x) - 3x 15 = x x = 15
4x+9 = 7x+3 4x-7x = 3-9 -3x = -6 x = 2
3x-3x+4x^2+8x=4x^2+8x
3x + (-2 + 4x) = -2 + 7x
