Q. If 8x−y=−10 \mathbf{8 x}-\mathbf{y}=-\mathbf{1 0} is a true equation, what would be the value of 4+8x−y? \mathbf{4}+\mathbf{8 x}-\mathbf{y} ? \newlineAnswer:
  1. Add 44 to both sides: We are given the equation 8x−y=−108x - y = -10. To find the value of 4+8x−y4 + 8x - y, we can simply add 44 to both sides of the given equation.\newlineCalculation: 8x−y+4=−10+48x - y + 4 = -10 + 4
  2. Simplify right side: Simplify the right side of the equation by adding −10-10 and 44.\newlineCalculation: 8x−y+4=−68x - y + 4 = -6
  3. Final value: Now we have the expression 8x−y+48x - y + 4 simplified to −6-6, which is the value of 4+8x−y4 + 8x - y.
