Q. Solve using elimination.9x+8y=36x+8y=−6(_____, _____)
Write Equations: Write down the system of equations to be solved using elimination.9x+8y=36x+8y=−6
Eliminate Variable: To use elimination, we need to eliminate one of the variables. We can subtract the second equation from the first equation to eliminate the y variable.(9x+8y)−(6x+8y)=3−(–6)
Perform Subtraction: Perform the subtraction to eliminate the y variable.9x−6x+8y−8y=3+6
Simplify Equation: Simplify the resulting equation. 3x=9
Solve for x: Solve for x by dividing both sides of the equation by 3.33x=39
Substitute x: Calculate the value of x.x=3
Calculate y: Now that we have the value of x, we can substitute it into one of the original equations to find the value of y. We'll use the first equation for this purpose.9(3)+8y=3
Isolate y Term: Perform the multiplication to solve for y.27+8y=3
Calculate y Value: Subtract 27 from both sides of the equation to isolate the term with y.8y=3−27
Divide to Solve y: Calculate the value of y.8y=−24
Divide to Solve y: Calculate the value of y.8y=−24Divide both sides of the equation by 8 to solve for y.y=8−24
Divide to Solve y: Calculate the value of y. 8y=−24Divide both sides of the equation by 8 to solve for y. y=−824Calculate the value of y. y=−3
