Answer:
Step-by-step explanation:
X+3y= -5
4x-y= -33
1. X=-3y-5 (move the variable to the other side of the equation)
2. 4(-3y-5)-y= -33 (substitute the value of x)
3. -12y-20-y= -33 (cross multiply)
4. -13y-20= -33 (reduce)
5. -13y= -33+20 (isolate variable)
6. -13y= 13 (addition or subtraction)
7. Y= 13÷(-13) (divide)
8. Y= -1
9. X+3(-1)= -5 (substitute value into other equation)
10. X-3= -5 (multiply)
11. X= -5+3 (move to the other side)
12. X= -2 Y= -1
