2x+3=x+5
Since x contains the variable to solve for, move it to the left-hand side of the equation by subtracting x from both sides.
2x+3-x=5
Since 2x and -x are like terms, add -x to 2x to get x.
x+3=5
Since 3 does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting 3 from both sides.
x=-3+5
Add 5 to -3 to get 2.
x=2
2x-3 = x+5 2x-x = 8 x = 8
3x-2 = 2x+3 3x-2x = 3+2 x = 5
x^3=2x+5 x^3-2x-5=0 Graph the equation or use a calculator. x= 2.09455148
If: 2x = x+5 Then: x = 5
x2 + 2x - 15 = 0(x + 5) (x - 3) = 0x = -5x = +3
2x+3 = 3x+5 2x-3x = 5-3 -x = 2 x = -2
2x+2=x+5 x=3
2x-3 = x+5 2x-x = 8 x = 8
6x + 3 = 2x + 5 4x = 2 x=1/2
2x+5=11 2x=6 x=3
Simplify 4x + 3 = 2x + 8 2x = 5 x =2½
5 - 2x = 8 x = -1 and 1/2 4x = 6 x = 6/4 or 3/2
X=-1
the answer is 7
x=1.
2x-4
2x-3=x+2 2x-x=2+3 x=5
