Consider the system of equations

5x + y = 31

3x + 4y = -39

Take your expression for y from part (a), and substitute it into the second equation. Solve for x and y.

Enter your answer as the ordered pair(x,y)

5x + y = 31 subtract 5x from both sides of the equation

y = 31 - 5x substitute this value of 'y' into tht e second equation

3x + 4 ( 31 - 5x) = - 39 Now solve this equation for 'x' then y = 31 - 5x and you are done !
