Answer
\( x = 4 \) and \( x = 7 \)
Solution
Solve the equation \( \frac{2}{3}=\frac{x}{6} \).
Solve the equation by following steps:
- step0: Solve for \(x\):
\(\frac{2}{3}=\frac{x}{6}\)
- step1: Swap the sides:
\(\frac{x}{6}=\frac{2}{3}\)
- step2: Multiply both sides of the equation by \(6:\)
\(\frac{x}{6}\times 6=\frac{2}{3}\times 6\)
- step3: Multiply the terms:
\(x=\frac{2\times 6}{3}\)
- step4: Evaluate:
\(x=4\)
Solve the equation \( \frac{8}{2}=\frac{28}{x} \).
Solve the equation by following steps:
- step0: Solve for \(x\):
\(\frac{8}{2}=\frac{28}{x}\)
- step1: Find the domain:
\(\frac{8}{2}=\frac{28}{x},x\neq 0\)
- step2: Divide the terms:
\(4=\frac{28}{x}\)
- step3: Swap the sides:
\(\frac{28}{x}=4\)
- step4: Cross multiply:
\(28=x\times 4\)
- step5: Simplify the equation:
\(28=4x\)
- step6: Rewrite the expression:
\(4\times 7=4x\)
- step7: Evaluate:
\(7=x\)
- step8: Swap the sides:
\(x=7\)
- step9: Check if the solution is in the defined range:
\(x=7,x\neq 0\)
- step10: Find the intersection:
\(x=7\)
The solutions to the given equations are:
1. \( x = 4 \)
2. \( x = 7 \)

Beyond the Answer
To find the value of \( x \) in the first equation, we can cross-multiply: \[ 2 \times 6 = 3 \times x \] \[ 12 = 3x \] Dividing both sides by 3 gives us \( x = 4 \). Now, for the second equation, we cross-multiply again: \[ 8 \times x = 2 \times 28 \] \[ 8x = 56 \] Dividing both sides by 8 gives us \( x = 7 \). So the two values of \( x \) found from each equation are 4 and 7!
