Step-by-step explanation:
<u>Step 1: Define Equation</u>
2/3x = 27
<u>Step 2: Solve for </u><em><u>x</u></em>
- Divide 2/3 on both sides: x = 81/2
<u>Step 3: Check</u>
<em>Plug in x into the original equation to verify it's a solution.</em>
- Substitute in <em>x</em>: 2/3(81/2) = 27
- Multiply: 27 = 27
Here we see that 27 does indeed equal 27.
∴ x = 81/2 is the solution to the equation.
