Answer:
-3 is the answer
Step-by-step explanation:
distribute the value of n
3+4-5×2
=7-10
=-3
The next numbers are 32 and -64 the pattern multiplies by -2
9x - 2y = 11 ... (i)
5x - 2y = 15 ... (ii)
Subtracting equation (ii) from (i) we get;
4x + 0 = -4
4x=-4 , x = -1
Replacing x = -1 in equation (i) we get;
9(-1) - 2y = 11
-9 - 2y = 11
-2y = 20
y = 20 ÷ -2 = -10
The solution to the system of equations is (-1,-10).
