Q. Which ordered pair is the solution to this system of eque{x=21y+52x+3y=−14
Express x in terms of y: We have the system of equations:1. x=21y+52. 2x+3y=−14First, let's express x from the first equation in terms of y.
Substitute and eliminate x: Now, substitute the expression for x from the first equation into the second equation to eliminate x and solve for y.2(21y+5)+3y=−14
Distribute and combine terms: Distribute the 2 on the left side of the equation:2(21)y+2⋅5+3y=−14y+10+3y=−14
Solve for y: Combine like terms:y+3y=−14−104y=−24
Substitute y back into first equation: Divide both sides by 4 to solve for y:44y=4−24y=−6
Find x value: Now that we have the value of y, we can substitute it back into the first equation to solve for x:x=(21)(−6)+5
Final ordered pair: Perform the multiplication and addition to find x:x=−3+5x=2
Final ordered pair: Perform the multiplication and addition to find x:x=−3+5x=2We have found the values of x and y that satisfy the system of equations. The ordered pair is (2,−6).
