Q. Solve by substitution{3x−2y=14y=5xA. (−2,−10)B. (−2,10)C. (2,−10)D. infinitely many solutions
Substitute Equations: Substitute the second equation into the first equation.Given the system of equations:3x−2y=14y=5xSubstitute y=5x into the first equation:3x−2(5x)=14
Simplify and Solve: Simplify the equation and solve for x.3x−10x=14−7x=14Divide both sides by −7 to find x:x=−714x=−2
Find Value of y: Substitute the value of x back into the second equation to find y.y=5xy=5(−2)y=−10
Write Ordered Pair: Write the solution as an ordered pair.The solution to the system of equations is x=−2 and y=−10.The ordered pair is (−2,−10).
