Question

use the elimination method to solve the system of equations. Write ur asnwer as an ordered pair

1) 3x+y=-1
    5x-y=9

matheducatormcg · Answer

because these equations have the same variables, and the coefficient of the y  from the first equation is opposite the coefficient of the y from the 2nd equation.
Add the equations straight down and the y variable cancels out. you then can solve for x.
after you have x, substitute the value into either of the original equations and find y.

matheducatormcg · Answer

coefficient is the number in front of the variable.
