Step-by-step explanation:
6(-2)+5(1)=-7
-12+5=-7 this is correct
2(-2)-4(1)=-8
-4-4=-8 this is also correct
The answer for this question is 2 and 3
Answer:
4x + y = −2 --> 4x = -y - 2
4x + 6y = 44
Substitute 4x in the 2. equation.
(-y - 2) + 6y = 44
5y - 2 = 44
5y = 46
y = 9.2
4x = -9.2 - 2
4x = -11.2
x = -2.8
