Start by putting like terms on each side, so the x values on one side and the numbers on the other side. The calcualte as appropriate to give one x value and one number value.
-3x + 1 + 4x + 2 -2 x - 14 + 5
x -3x + 4x - 2x + 5x + 1 + 2 - 14
4x - 11

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?
