Q. How many solutions does the given system of equations have?\newliney7=6(x+1)y-7=-6(x+1)\newline4y+24x+28=04y+24x+28=0
  1. Write Equations: Write down the given system of equations.\newlineThe system of equations is:\newliney7=6(x+1)y - 7 = -6(x + 1)\newline4y+24x+28=04y + 24x + 28 = 0
  2. Simplify First Equation: Simplify the first equation to express yy in terms of xx.y7=6(x+1)y - 7 = -6(x + 1)y=6x6+7y = -6x - 6 + 7y=6x+1y = -6x + 1
  3. Substitute into Second Equation: Substitute the expression for yy from the first equation into the second equation.4(6x+1)+24x+28=04(-6x + 1) + 24x + 28 = 024x+4+24x+28=0-24x + 4 + 24x + 28 = 0
  4. Combine Like Terms: Simplify the equation by combining like terms. \newline24x+24x+4+28=0-24x + 24x + 4 + 28 = 0\newline0x+32=00x + 32 = 0
  5. Solve for x: Solve the simplified equation for x.\newlineSince there is no x term left (0x=00x = 0), we only have a constant left on the left side of the equation.\newline32=032 = 0\newlineThis is a contradiction because 3232 cannot equal 00.
  6. Conclude No Solutions: Conclude the number of solutions based on the contradiction.\newlineSince we arrived at a contradiction, it means that there are no values of xx and yy that can satisfy both equations simultaneously. Therefore, the system of equations has no solutions.
