Question

Solve the equation below for x and check your solution.

4x+3=x​

Answer 1

x= -1

Explanation:

4x+3=x​

we subtract x to both sides of the equation:

4x -x +3 = x-x

we have:

3x +3 = 0

we subtract 3 to both sides of the equation:

3x +3 -3 = -3

3x = -3

we divide by 3 both sides of the equation

3x/3 = -3/3

x= -1

we test the result in the original equation:

4x+3=x​

4*(-1) + 3 = -1

-4 +3 = -1

-1 = -1

so finally x= -1
