Q. Rewrite the following equation in standard form.\newliney=5x+2y = 5x + 2\newlineHint: The standard form of a linear equation is Ax+By=CAx + By = C where AA and BB are not both zero, and AA, BB, and CC are integers whose GCF is 11.
  1. Given Equation: Start with the given equation.\newliney=5x+2y = 5x + 2\newlineWe need to rearrange this equation into the standard form, which is Ax+By=CAx + By = C.
  2. Rearrange Equation: Move the term 5x5x to the left side of the equation by subtracting 5x5x from both sides.\newliney5x=5x+25xy - 5x = 5x + 2 - 5x\newlineThis simplifies to:\newline5x+y=2-5x + y = 2
  3. Make Coefficient Positive: The standard form of a linear equation should have the xx-term first, followed by the yy-term, and then the constant. However, the coefficient of xx should be positive. Multiply the entire equation by 1-1 to make the coefficient of xx positive.\newline1(5x+y)=1(2)-1(-5x + y) = -1(2)\newlineThis simplifies to:\newline5xy=25x - y = -2
  4. Check Coefficients: To ensure that the coefficients are integers whose greatest common factor (GCF) is 11, we check the coefficients 55, 1-1, and the constant 2-2. The GCF of these numbers is indeed 11.
