Q. Solve the system of equations.−4x+3y=−2y=x−1x=□y=□
Identify Equations: Identify the given system of equations.We have a system of three equations:1) −4x+3y=−22) y=x−13) x=□4) y=□We need to find the values of x and y that satisfy all three equations.
Substitute and Simplify: Substitute the second equation into the first equation.Since y=x−1, we can replace y in the first equation with x−1:−4x+3(x−1)=−2
Solve for x: Simplify the equation and solve for x.−4x+3x−3=−2Combine like terms:−x−3=−2Add 3 to both sides:−x=1Multiply both sides by −1 to solve for x:x=−1
Substitute for y: Substitute the value of x into the second equation to find y.Since y=x−1, we substitute x=−1:y=−1−1y=−2
Verify Solution: Verify the solution with the original system of equations.We need to check if x=−1 and y=−2 satisfy all three equations.For the first equation:−4(−1)+3(−2)=−24−6=−2−2=−2 (True)For the second equation:y=x−1−2=−1−1−2=−2 (True)Since the third and fourth equations are placeholders for the solutions, we have found the correct values for x and y.
