That is not an equation and cannot be solved. An equation states that two things are equal, and it has an equal sign, which looks like this = for example, I could say that 2x - 7 = 5 in which case I would have an equation that I could easily solve
as follows: add 7 to both sides, which gives you
2x = 12, then divide both sides by 2 which gives you
x = 6.
2x+12-3x = 5 2x-3x = 5-12 -x = -7 x = 7
4X - 7 = 2X + 5 subtract 2X from each side 4X - 2X - 7 = 2X - 2X + 5 2X - 7 = 5 add 7 to each side 2X - 7 + 7 = 5 + 7 2X = 12 divide both sides integers by 2 (2/2)X = 12/2 X = 6 --------------check in original equation 4(6) - 7 = 2(6) + 5 24 - 7 = 12 + 5 17 = 17 -----------checks
3X+2=2X-5 -2 -2 __________ 3X= 2X-7 -2X -2X __________ X=-7 Check: 3(-7)+2=2(-7)-5 -19=-19 :)
x + 2x - x + 7 = 4x - x + 2 Clean this up. 2x + 7 = 3x + 2 Subtract 2x from both sides. 7 = x + 2 Now subtract 2 from both sides. 5 = x ◄ Check 5 + 2(5) - 5 + 7 = 4(5) - 5 + 2 5 + 10 - 5 + 7 = 20 - 5 + 2 15 - 5 + 7 = 15 + 2 10 + 7 = 17 ■
2x + 7 + 5 = 2x + 12 = 2*x + 2*6 = 2*(x+6)
f(x)= (x-7) /(-2x+7)(2x+5) set -2x+7=0 -2x=-7 x=7/2 set 2x+5=0 2x=-5 x=-5/2 x=7/2 and x=-5/2 are vertical asymptotes.
4x - 7 = 2x + 5 2x - 7 = 5 2x = 12 x = 6.
6x-8+2x-5 = 7-2x 6x+2x+2x = 7+8+5 10x = 20 x = 20/10 x = 2
-3(x-5)=2x
(The original question was misphrased.) 4x-7 = 2x+5 resolves as 2x-7 = 5 2x = 12 x = 6
2x+12-3x = 5 2x-3x = 5-12 -x = -7 x = 7
4X - 7 = 2X + 5 subtract 2X from each side 4X - 2X - 7 = 2X - 2X + 5 2X - 7 = 5 add 7 to each side 2X - 7 + 7 = 5 + 7 2X = 12 divide both sides integers by 2 (2/2)X = 12/2 X = 6 --------------check in original equation 4(6) - 7 = 2(6) + 5 24 - 7 = 12 + 5 17 = 17 -----------checks
x3 + 2x2 - 35x = x(x2 + 2x - 35) = x(x + 7)(x - 5)
3X+2=2X-5 -2 -2 __________ 3X= 2X-7 -2X -2X __________ X=-7 Check: 3(-7)+2=2(-7)-5 -19=-19 :)
x + 2x - x + 7 = 4x - x + 2 Clean this up. 2x + 7 = 3x + 2 Subtract 2x from both sides. 7 = x + 2 Now subtract 2 from both sides. 5 = x ◄ Check 5 + 2(5) - 5 + 7 = 4(5) - 5 + 2 5 + 10 - 5 + 7 = 20 - 5 + 2 15 - 5 + 7 = 15 + 2 10 + 7 = 17 ■
2x + 7 + 5 = 2x + 12 = 2*x + 2*6 = 2*(x+6)
2x + 52 = 7 2x + 25 = 7 2x = 7 - 25 2x = -18 x = -18/2 x = -9
