Full solution

Q. 2x3y=12x-3y=-1\newliney=x1y=x-1
  1. Set Up Equations: We have a system of two linear equations:\newline11) 2x3y=12x - 3y = -1\newline22) y=x1y = x - 1\newlineLet's solve the second equation for yy and substitute it into the first equation.
  2. Substitute and Simplify: Substitute yy from the second equation into the first equation: 2x3(x1)=12x - 3(x - 1) = -1 Now, let's simplify and solve for xx.
  3. Isolate xx: Distribute the 3-3 across the parentheses: 2x3x+3=12x - 3x + 3 = -1 Combine like terms: x+3=1-x + 3 = -1
  4. Find yy: Add xx to both sides to isolate the constant on the right side:\newline3=x13 = x - 1\newlineNow, solve for xx by adding 11 to both sides:\newlinex=3+1x = 3 + 1\newlinex=4x = 4
  5. Final Solution: Now that we have the value of xx, we can substitute it back into the second equation to find yy:y=x1y = x - 1y=41y = 4 - 1y=3y = 3
