-4(9)(-5) = (-36)(-5) because -4(9) = -36. (-36)(-5) = 180
Answer:
10 + 5
Step-by-step explanation:
If you are subtracting a negative then it become adding a positive. A way to remember this is because it has matching socks.
Given,
The linear pair of the equation is,

Required
The solution of the linear equation.
Taking the equation first as,

Substituting the value of y in second equation then,

Substituting the value of x in first equation then,

Hence, the solution of the system is (1, -10).
