Q. If 9x−10y=10 is a true equation, what would be the value of 9x−10y−7?□
Given Equation: We are given that 9x−10y=10 is a true equation. We need to find the value of 9x−10y−7.Since 9x−10y=10, we can subtract 7 from both sides of the equation to find the value of 9x−10y−7.9x−10y−7=10−7
Subtract 7: Perform the subtraction on the right side of the equation. 9x−10y−7=3
Perform Subtraction: We have found the value of 9x−10y−7. It is equal to 3.
