Answer:
-36
Step-by-step explanation:
since you say x=-1and y=3, you will put 1 in where x is and 3 where y is ,that is 2(3×-1]-5×3)
2(-3-15) then you subtract the bracket, that is 3-15 and it will give you -18. Then you use the 2 outside the bracket to multiply -18 ,that is 2×-18then it will give -36
