Explain Bot To solve the equation 3x + 8 = 20, we need to isolate the variable x.
Step 1: Start by subtracting 8 from both sides of the equation to eliminate the constant term on the left side:
3x + 8 - 8 = 20 - 8
This simplifies to:
3x = 12
Step 2: Now, to isolate x, divide both sides of the equation by the coefficient of x, which is 3:
(3x)/3 = 12/3
This simplifies to:
x = 4
Therefore, the solution to the equation 3x + 8 = 20 is x = 4.
