Q. Solve the system of equations.\newline7y+10x8=02y5x18=0\begin{aligned} &7y+10x - 8=0 \\\\ & 2 y-5x-18=0 \end{aligned}
  1. Calculate Total Tape: First, we need to determine the total amount of electrical tape the electrician needs and the amount of tape on each roll.\newlineTotal amount of electrical tape needed: 8,000cm8,000\,\text{cm}\newlineAmount of tape on each roll: 2,000cm2,000\,\text{cm}
  2. Determine Number of Rolls: Next, we use division to calculate the number of rolls the electrician should order.\newlineNumber of rolls needed =Total amount of tape neededAmount of tape on each roll= \frac{\text{Total amount of tape needed}}{\text{Amount of tape on each roll}}\newlineNumber of rolls needed =8,000cm2,000cm= \frac{8,000\,\text{cm}}{2,000\,\text{cm}}
  3. Perform Division: Perform the division to find the number of rolls.\newlineNumber of rolls needed = 44
