Q. Find the solution to the system of equations.\newlineYou can use the interactive graph below to find the solution.\newline{2x+2y=43x+3y=18x=y= \begin{array}{l} \left\{\begin{array}{l} -2 x+2 y=-4 \\ 3 x+3 y=-18 \end{array}\right. \\ x=\square \\ y=\square \end{array}
  1. Write Equations: Write down the system of equations.\newlineThe system of equations is given by:\newline2x+2y=4-2x + 2y = -4\newline3x+3y=183x + 3y = -18
  2. Simplify Equations: Simplify the equations if possible.\newlineBoth equations can be simplified by dividing by the common factor of the coefficients.\newlineFor the first equation, divide by 22:\newline2x2+2y2=42\frac{-2x}{2} + \frac{2y}{2} = \frac{-4}{2}\newlineWhich simplifies to:\newlinex+y=2-x + y = -2\newlineFor the second equation, divide by 33:\newline3x3+3y3=183\frac{3x}{3} + \frac{3y}{3} = \frac{-18}{3}\newlineWhich simplifies to:\newlinex+y=6x + y = -6
  3. Solve Simplified System: Solve the simplified system of equations.\newlineWe now have the system:\newlinex+y=2-x + y = -2\newlinex+y=6x + y = -6\newlineWe can add the two equations together to eliminate xx:\newline(x+y)+(x+y)=2+(6)(-x + y) + (x + y) = -2 + (-6)\newlineThis simplifies to:\newline2y=82y = -8
  4. Solve for y: Solve for y.\newlineDivide both sides of the equation by 22 to solve for y:\newline2y2=82\frac{2y}{2} = \frac{-8}{2}\newliney=4y = -4
  5. Substitute and Solve for x: Substitute the value of yy back into one of the simplified equations to solve for xx. Using the equation x+y=6x + y = -6, substitute y=4y = -4: x+(4)=6x + (-4) = -6 x4=6x - 4 = -6 Add 44 to both sides to solve for xx: x4+4=6+4x - 4 + 4 = -6 + 4 x=2x = -2
