3x+5 = 2x+13 3x-2x = 13-5 x = 8
(2x - 5)(2x - 5) or (2x - 5) squared
Blue is not a solution.
Simplify 4x + 3 = 2x + 8 2x = 5 x =2½
6x - 8 + 2x - 5 = 7 - 2x ?
4+2x-2x+1=13+6 Combine like terms. (4+1=5; 2x-2x=0; 13+6=19) 5=19 This problem has no solution.
x + 2x + 5 = x +19 3x + 5 = x +19 3x - x = 19 - 5 2x = 14 x = 7
2x+3 = 3x+5 2x-3x = 5-3 -x = 2 x = -2
3x-5
4x + 5 = 2x + 19Subtract 5 from each side:4x = 2x + 14Subtract 2x from each side:2x = 14Divide each side by 2:x = 7
Not calculus. x + 2x + 5 = x + 19 3x + 5 = x + 19 Combine like terms 2x + 5 = 19 Subtract x from both sides 2x = 14 Subtract 5 from both sides x = 7 Divide both sides by 2.
X = 6
x = -5
7
5 - 2x = 8 x = -1 and 1/2 4x = 6 x = 6/4 or 3/2
3X+2=2X-5 -2 -2 __________ 3X= 2X-7 -2X -2X __________ X=-7 Check: 3(-7)+2=2(-7)-5 -19=-19 :)
X=2
