REWRITE THE EQUATION \frac{4x}{3x-12}+3=10 IN TWO EQUATIONS JOINED BY "AND."

1 answer

To rewrite the equation \(\frac{4x}{3x-12} + 3 = 10\) in two equations joined by "AND," we need to isolate the fraction and then set up a corresponding equation that reflects the relationship.

  1. Start with the original equation: \[ \frac{4x}{3x-12} + 3 = 10 \]

  2. Subtract 3 from both sides to isolate the fraction: \[ \frac{4x}{3x-12} = 10 - 3 \] \[ \frac{4x}{3x-12} = 7 \]

Now, we have two statements that can be expressed as separate equations:

  • The fraction equation: \[ \frac{4x}{3x-12} = 7 \]

  • The condition that we simplified (the right side of the original equation): \[ 3x - 12 \neq 0 \] (because the denominator cannot equal zero)

Now, we can combine these into a statement with "AND":

\[ \frac{4x}{3x-12} = 7 \quad \text{AND} \quad 3x - 12 \neq 0 \]

So the final answer is:

\[ \frac{4x}{3x-12} = 7 \quad \text{AND} \quad 3x \neq 12 \]
