The value of x in the equation is -24
linear algebraic equations are equation with unknown. The unknown is always represented by letters. The highest power of the unknown is 1
Solving
2x + 20 = x - 4
subtract x from both sides
2x - x + 20 = x - x -4
= x + 20 = -4
subtract 20 from both sides
x + 20 - 20 = -4 - 20
x = -24
Therefore the value of x in the equation is -24.
