Q. Solve the system of equations.3x−4y=818x−5y=10x=□y=□
Step 1: Eliminate variable 'x': Identify the variable to eliminate. We can eliminate 'x' by multiplying the first equation by 6 to match the coefficient of 'x' in the second equation.Calculation: 6×(3x−4y)=6×8This gives us 18x−24y=48.
Step 2: Subtract equations to eliminate 'x': Subtract the modified first equation from the second equation to eliminate 'x'.Calculation: (18x−5y)−(18x−24y)=10−48This simplifies to 19y=−38.
Step 3: Solve for 'y': Solve for 'y'.Calculation: Divide both sides of the equation by 19 to get y=19−38, which simplifies to y=−2.
Step 4: Substitute 'y' into first equation: Substitute y=−2 into the first original equation to solve for 'x'.Calculation: 3x−4(−2)=8This simplifies to 3x+8=8.
Step 5: Solve for 'x': Solve for 'x'.Calculation: Subtract 8 from both sides to get 3x=0, then divide by 3 to get x=0.
Step 6: Write the solution as a coordinate point: Write the solution as a coordinate point.The solution is (0,−2).
