Q. 24−6y=2x6(y−2)=3+xConsider the system of equations. If (x,y) is the solution to the system, then what is the value of y+x ?
Solve for x: Solve the first equation for x.We have 24−6y=2x. To solve for x, we divide both sides by 2.x=224−6yx=12−3y
Substitute x into second equation: Substitute the expression for x into the second equation.The second equation is 6(y−2)=3+x. We substitute x with 12−3y.6(y−2)=3+(12−3y)
Simplify and solve for y: Simplify and solve for y.Expanding the left side, we get:6y−12=3+12−3yCombining like terms, we get:6y+3y=3+12+129y=27Dividing both sides by 9, we get:y=927y=3
Substitute y into x expression: Substitute the value of y into the expression for x.We have x=12−3y. Now that we know y=3, we substitute it in.x=12−3(3)x=12−9x=3
Find y+x: Add the values of x and y to find y+x.y+x=3+3y+x=6
