No. x=3. (5x3 is 15 or 5x =15-3=12)
-5x=3+y x=-1/5y-3/5
3=x+3-5x subtract 3 from both sides 0=x-5x combine 0=-4x 0=x
2X - 3 + 3X = 37 add the X terms together 5X - 3 = 37 add 3 to each side 5X = 40 divide both sides by 5 X = 8 check in original equation 2(8) - 3 + 3(8) = 37 16 - 3 + 24 = 37 13 + 24 = 37 37 = 37 checks
That all depends.Is it:ln (2x+9) = ln (5x)If it is, the solution can be found by solving 2x+9 = 5x, in which case the answer is x = 3.
5x-3=37 (Original Equation) 5x=40(Add 3 to the right side) x=8(Divide 40 by 5)
5x = 15 so x = 15/5 = 3
No. x=3. (5x3 is 15 or 5x =15-3=12)
5x-3 = 11+12x 5x-12x = 11+3 -7x = 14 x = -2
-5x=3+y x=-1/5y-3/5
3=x+3-5x subtract 3 from both sides 0=x-5x combine 0=-4x 0=x
2X - 3 + 3X = 37 add the X terms together 5X - 3 = 37 add 3 to each side 5X = 40 divide both sides by 5 X = 8 check in original equation 2(8) - 3 + 3(8) = 37 16 - 3 + 24 = 37 13 + 24 = 37 37 = 37 checks

x2-5x = 24 x2-5x-24 = 0 (x-8)(x+3) = 0 x = 8 or x -3
5x-2=13 +2 +2 5x=15 x=3
2x2+5x-3 = 0 (2x-1)(x+3) = 0 x = 1/2 or x -3
In the equation 43X +2=5X, X=-1/19.
