Question

solve each equation. 20) 19 + x = 23 what is the value of x? x = 3 x = 5 x = 4 x = 2

Explanation:

Step1: Isolate the variable x

Subtract 19 from both sides of the equation $19 + x=23$. So, $19 + x-19=23 - 19$.

Step2: Simplify both sides

On the left - hand side, $19-19 + x=x$, and on the right - hand side, $23 - 19 = 4$. So $x = 4$.

Answer:

$x = 4$
