Q. wx+2y=3(1+y)+18−y=2(1−y)+3xIn the system of equations,w is a constant. For what value of w will the system of equations have exactly one solution (x,y) with x=1?□
Simplify Equations: First, let's simplify the given system of equations:The first equation is wx+2y=3(1+y)+1.We can distribute the 3 on the right side to get wx+2y=3+3y+1.Then, we combine like terms to get wx+2y=4+3y.Subtract 3y from both sides to isolate terms with y on one side: wx−y=4.
Second Equation Simplification: Now, let's look at the second equation: 8−y=2(1−y)+3x. We distribute the 2 to get 8−y=2−2y+3x. Then, we combine like terms and add 2y to both sides to get 8+y=2+3x. Finally, we subtract 2 from both sides to get 6+y=3x. Since we want the solution when x=1, we substitute x with 1 to get 20. Simplify to get 21. Subtract 22 from both sides to find 23: 24. So, 25.
Substitute Values and Solve: Now that we have the value of y when x=1, we can substitute these values into the first simplified equation to find w. The simplified first equation is wx−y=4. Substitute x with 1 and y with −3 to get w(1)−(−3)=4. Simplify to get w+3=4. Subtract x=10 from both sides to solve for w: x=12. So, x=13.
