Q. If 8x−y=−10 is a true equation, what would be the value of 4+8x−y?Answer:
Add 4 to both sides: We are given the equation 8x−y=−10. To find the value of 4+8x−y, we can simply add 4 to both sides of the given equation.Calculation: 8x−y+4=−10+4
Simplify right side: Simplify the right side of the equation by adding −10 and 4.Calculation: 8x−y+4=−6
Final value: Now we have the expression 8x−y+4 simplified to −6, which is the value of 4+8x−y.
