Question

Solve the following system of equations. Express your answer as an ordered pair in the format (a,b).
2x+7y=-1
4x-3y=-19

Answer 1

i got (-4,1), is that right?

Answer 2

yes

Answer 3

You would multiply the coefficient of y in this question which is 7 and 3 by the equations. You would type the 7 by the equation that has 3y in it and multiply 3 by the equation has 7y then rewrite it with the new values and then add them in a column and solve them. The y will deleted and x is left and then solve and find x and then substitute in either equation and find y
