Write a system of equations to describe the situation below, solve using elimination, and fill in the blanks.At a historical landmark, candles are used to simulate an authentic atmosphere. A volunteer is currently putting new candles in the candle holders. On the east side, he replaced candles in 7 small candle holders and 3 large candle holders, using a total of 45 candles. On the west side, he replaced the candles in 19 small candle holders and 19 large candle holders, for a total of 209 candles. How many candles does each candle holder hold?Each small candleholder holds _ candles, and each large one holds _ candles.
Q. Write a system of equations to describe the situation below, solve using elimination, and fill in the blanks.At a historical landmark, candles are used to simulate an authentic atmosphere. A volunteer is currently putting new candles in the candle holders. On the east side, he replaced candles in 7 small candle holders and 3 large candle holders, using a total of 45 candles. On the west side, he replaced the candles in 19 small candle holders and 19 large candle holders, for a total of 209 candles. How many candles does each candle holder hold?Each small candleholder holds _ candles, and each large one holds _ candles.
Equation 1: Let's denote the number of candles a small candle holder holds as s and the number of candles a large candle holder holds as l. The volunteer replaced candles in 7 small candle holders and 3 large candle holders on the east side, using a total of 45 candles. This gives us the equation 7s+3l=45.
Equation 2: On the west side, the volunteer replaced the candles in 19 small candle holders and 19 large candle holders, for a total of 209 candles. This gives us the equation 19s+19l=209.
Eliminate Variable: We now have a system of two equations. We need to eliminate one of the variables, s or l. We choose to eliminate l because its coefficients are the same in both equations.Step 4: To eliminate l, we can subtract the first equation from the second equation. This gives us 19s+19l−(7s+3l)=209−45. Simplifying this, we get 12s+16l=164.
