Solve for X:
4x=81
To solve the equation 4x=81, we need to isolate x. We do this by dividing both sides of the equation by the coefficient of x, which is 4:
- Step 1: Write the original equation: 4x=81.
- Step 2: Divide both sides by 4 to solve for x:
x=481
- Step 3: Simplify the right-hand side by multiplying fractions, recalling that dividing by a number is equivalent to multiplying by its reciprocal:
x=81×41=8×41×1=321
Thus, the solution to the equation is x=321.
