Sagot :
Answer:
x = -4 and y = -1
Step-by-step explanation:
Adding the equations,
4x + 0y = -16
4x = -16
x = -4
Plugging x = -4 into the second equation,
-4 + y = -5
y = -1
Therefore, x = -4 and y = -1
Answer :
- Value of x is-4
- Value of y is-1
Explaination :
Here we have been given with two equations and we have to calculate the value of x and y by using elimination method.
- 3x - y = -11 (Equation No 1)
- x + y = -5 (Equation No 2)
★ From Equation No 2:-
>> x + y = -5
>> x = -y - 5
★ In Equation No 1:-
Substituting the value of x which we got above as (-y - 5) here.
>> 3x - y = -11
>> 3 (-y - 5) - y = -11
>> 3 × (-y - 5) - y = -11
>> -3y - 15 - y = -11
>> -4y - 15 = -11
>> -4y = 15 - 11
>> -4y = 4
>> y = -4/4
>> y = -1
★ Finding out value of y:-
>> x = -y - 5
>> x = -(-1) - 5
>> x = 1 - 5
>> x = -4 [tex] \: [/tex]
