Solve for x x+3+2x=-1+3x+4

$x + 3 + 2 x = - 1 + 3 x + 4$

Step 1

Add $x$ and $2 x$ .

$3 x + 3 = - 1 + 3 x + 4$

Step 2

Add $- 1$ and $4$ .

$3 x + 3 = 3 x + 3$

Step 3

Move all terms containing $x$ to the left side of the equation.

Subtract $3 x$ from both sides of the equation.

$3 x + 3 - 3 x = 3$

Combine the opposite terms in $3 x + 3 - 3 x$ .

Subtract $3 x$ from $3 x$ .

$0 + 3 = 3$

Add $0$ and $3$ .

$3 = 3$

Step 4

Since $3 = 3$ , the equation will always be true for any value of $x$ .

All real numbers

Step 5

The result can be shown in multiple forms.
