Multiply all words of the equation by using 2x, you get 4x+5/2x= -3 4x(2x)+5=-3(2x) 8x^2+6x+5=0 (finished the sq.) x^2+(6/8)x= -5/8 x^2+(6/8)x+(9/sixty 4)= -5/8+9/sixty 4 (x+(3/8))^2 = -31/sixty 4 (x+(3/8))= [+ or - i(squarert 31)]/8 x = [-(3/8) + or - i(squarert 31)]/8
Add -2X to both sides in order to group the Xs on the same side of the equation. Now, add 5 to both sides in order to group none-variables on the opposite side. You now have 4X - 2X = 3 + 5. Do the addition and subtraction: 2X = 8. Finally, multiply both sides of the equation by the inverse of 2, which is 1/2, in order to get 1X or X: 1/2 * 2X = 1/2 * 8.

Verified answer
4x - 5 = 2x + 3
4x - 2x = 3 + 5
2x = 8
x = 8/2 or 4
Answer: x = 4
Checking:
4(4) - 5 = 2(4) + 3
16 - 5 = 8 + 3
11 = 11

4x – 5 = 2x + 3
4x = 2x + 3 + 5
4x -2x = 8
2x = 8
x = 4
Solve the equation:
4x - 5 = 2x + 3
Add -2x to each side of the equation
4x - 5 - 2x = 2x + 3 - 2x
2x - 5 = 3
Add 5 to each side of the equation
2x - 5 + 5 = 3 + 5
2x = 8
Divide each side by 2
2x/2 = 8/2
x = 4
4x – 5 = 2x + 3
thus 4x - 2x = 3 + 5
thus 2x = 8
thus x = 8/2
thus x = 4
x=4
The solution is simple: Combine like terms and solve for x
4x - 2x = 5 + 3 is the same equation as we had before only we combined similar terms
2x = 8 is the simplification of the former.
x = 4 is the solution to the former.
Add -2X to both sides in order to group the Xs on the same side of the equation. Now, add 5 to both sides in order to group none-variables on the opposite side. You now have 4X - 2X = 3 + 5. Do the addition and subtraction: 2X = 8. Finally, multiply both sides of the equation by the inverse of 2, which is 1/2, in order to get 1X or X: 1/2 * 2X = 1/2 * 8.
X = 4.
x= 4
4x - 5 = 2x + 3
2x = 8
x = 4.
