Whenever a formula is used, begin by typing the formula you intend to use. Make sure to subscript where appropriate. Solve the system of equations using the substitution method. If the answer is a unique solution, present it as an ordered pair (x, y). If not, specify whether the answer is "no solution" or "infinitely many solutions".
-4x + y = 8
2x + 3y = -1
-4x + y = 8 .......................(1)
2x + 3y = -1 ...
A system of equations is solved by substitution.
