Question

What is the value of x in the solution to the following system of equation

x - y = -3
x + 3y = 5

Answer 1

@beastieman21 Can you help me with this?

Answer 2

one method by elimination
subtract the eqns this will eliminate the x you will have one eqn with one variable. when you solve for y use this value in any of the original eqn to find x,
did you get y = 2 x = -1?

by substitution
from the 1st eqn x = -3 + y
use this in the 2nd eqn x + 3y = 5
(-3+y) + 3y = 5
solve for y then use this value of y in x = -3 + y to get x

the 3rd method is graphing
for each line find the points when x = 0 what is y and when y = 0 what is x
this give 2 lines the solution is where they intersect

Answer 3

any method used will still give x = -1

Answer 4

x=-1
