2x+3 = 3x+5 2x-3x = 5-3 -x = 2 x = -2
2x + 2 = 3x - 57 = x
3X+2=2X-5 -2 -2 __________ 3X= 2X-7 -2X -2X __________ X=-7 Check: 3(-7)+2=2(-7)-5 -19=-19 :)
6x2+19x+10 = (2x+5)(3x+2) Length = 2x+5 Width = 3x+2
5x+2.
2x+3 = 3x+5 2x-3x = 5-3 -x = 2 x = -2
2x + 2 = 3x - 57 = x
3x-2 = 2x+3 3x-2x = 3+2 x = 5
3X+2=2X-5 -2 -2 __________ 3X= 2X-7 -2X -2X __________ X=-7 Check: 3(-7)+2=2(-7)-5 -19=-19 :)
6x2+19x+10 = (2x+5)(3x+2) Length = 2x+5 Width = 3x+2
3x+5 = 2x+13 3x-2x = 13-5 x = 8
5x+2.
-2x^4+16 +2x^4+9-3x^5=-3x^5+25. There is no "answer" because there is no equation.
3x + 2 + 2x = 7; 3x + 2x = 5x, so 5x + 2 = 7; 7-2=5, so 5x=5. 5x divided by 5 and 5 divided by 5 equals 1, so x equals 1.
x = 2
2x+x+5+3x-6=6x-1
3x + 5 = 5x + 2 Subtract 3x from both sides: 5 = 2x + 2 Subtract 2 from both sides: 3 = 2x Divide both sides by 2: 3/2 = x
