Question

$$19+21=20+2x$$

Solve for x

$x=10$

Steps for Solving Linear Equation

Add $19$ and $21$ to get $40$.

$$40=20+2x$$

Swap sides so that all variable terms are on the left hand side.

$$20+2x=40$$

Subtract $20$ from both sides.

$$2x=40-20$$

Subtract $20$ from $40$ to get $20$.

$$2x=20$$

Divide both sides by $2$.

$$x=\frac{20}{2}$$

Divide $20$ by $2$ to get $10$.

$$x=10$$
