-3x + 2 = -7x - 22 add 7x to both sides 4x + 2 = -22 subtract 2 from both sides 4x = -24 divide by 4 x = -6 ■
-3x + 2 = -7x - 22 add 7x to both sides 4x + 2 = -22 subtract 2 from both sides 4x = -24 divide by 4 x = -6
3x + 4 = 4x - 5 Add 5 to both sides: 3x + 9 = 4x Subtract 3x from both sides: 9 = x
3x/4 + x = 7x/4 because 4x/4 = x 3x/4 + 4x/4 = 7x/4
(6-4x)(x-2)+3x =6x-12-4x+8x+3x =5x-4
-3x + 2 = -7x - 22 add 7x to both sides 4x + 2 = -22 subtract 2 from both sides 4x = -24 divide by 4 x = -6 ■
-3x + 2 = -7x - 22 add 7x to both sides 4x + 2 = -22 subtract 2 from both sides 4x = -24 divide by 4 x = -6
- 3X - (- 4X) is the same as - 3X + 4X X(- 3 + 4) that is all the factoring needed there
3x + 4 = 4x - 5 Add 5 to both sides: 3x + 9 = 4x Subtract 3x from both sides: 9 = x
3x2 + 4x factors to x(3x + 4)
3x/4 + x = 7x/4 because 4x/4 = x 3x/4 + 4x/4 = 7x/4
5x-2x-3x+4x = (5-2-3+4)x = 4x
(6-4x)(x-2)+3x =6x-12-4x+8x+3x =5x-4
4x - 13 = 22 - 3x add 3x to both sides 7x - 13 = 22 add 13 to both sides 7x = 35 divide both sides by 7 x = 5
If: 3x+5 = 4x+1 Then: x = 4
3x+4-7x=5-4x+2 -4x+4=7-4x Adding 4x to each side yields: 4=7, which is not true, so there is no answer (a null set)
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?
