Q. 4x62y=4y+8x+2 4 x-6-2 y=4 y+8 x+2 \newline2x+3=11 2 x+3=11 \newlineConsider the given system of equations. If (x,y) (x, y) is the solution to the system, then what is the value of x+y x+y ?\newlineChoose 11 answer:\newline(A) 8-8\newline(B) 00\newline(C) 88\newlineD There are no solutions to this system of equations.
  1. Solve for x: First, let's solve the second equation for x.\newlineThe equation is 2x+3=112x + 3 = 11.\newlineSubtract 33 from both sides to isolate the term with xx.\newline2x+33=1132x + 3 - 3 = 11 - 3\newline2x=82x = 8\newlineNow, divide both sides by 22 to solve for xx.\newline2x2=82\frac{2x}{2} = \frac{8}{2}\newlinex=4x = 4
  2. Substitute xx into first equation: Next, we substitute the value of xx into the first equation to solve for yy. The first equation is 4x62y=4y+8x+24x - 6 - 2y = 4y + 8x + 2. \newlineSubstitute x=4x = 4 into the equation. \newline4(4)62y=4y+8(4)+24(4) - 6 - 2y = 4y + 8(4) + 2 \newline1662y=4y+32+216 - 6 - 2y = 4y + 32 + 2 \newlineSimplify both sides. \newline102y=4y+3410 - 2y = 4y + 34
  3. Get y terms on one side: Now, let's get all the y terms on one side and the constants on the other side.\newlineAdd 2y2y to both sides and subtract 3434 from both sides.\newline102y+2y34=4y+2y+343410 - 2y + 2y - 34 = 4y + 2y + 34 - 34\newlineCombine like terms.\newline24=6y-24 = 6y\newlineNow, divide both sides by 66 to solve for y.\newline246=6y6\frac{-24}{6} = \frac{6y}{6}\newline y=4y = -4
  4. Find x+yx + y: Finally, we find the value of x+yx + y. \newlineWe have x=4x = 4 and y=4y = -4. \newlinex+y=4+(4)x + y = 4 + (-4) \newlinex+y=0x + y = 0
