Question 416547
8x+3+x=5x+3+4x

Since 8x and x are like terms, add x to 8x to get 9x.
9x+3=5x+3+4x

Since 5x and 4x are like terms, add 4x to 5x to get 9x.
9x+3=9x+3

Since 9x contains the variable to solve for, move it to the left-hand side of the equation by subtracting 9x from both sides.
9x+3-9x=3

Since 9x and -9x are like terms, add -9x to 9x to get 0.
0+3=3

Remove the 0 from the polynomial; adding or subtracting 0 does not change the value of the expression.
3=3

Since 3=3, the equation will always be true.
Always True
