Answer: 50 and 5, respectively

Explanation:

For this problem, we are given x and y. With the x and y value given, all we have to do is to plug them into the expressions and solve.

5(x-2y) [plug in x=4 and y=-3]

5((4)-2(-3)) [combine like terms by using order of operations]

5(4+6)

5(10)=50

-----------------------------------------------------------------------------------------------------------

2x+y [plug in x=4 and y=-3]

2(4)+(-3) [combine like terms by using order of operations]

8-3=5

Now that we have plugged in x=4 and y=-3 into the two expressions, we get 50 for the first expression and 5 for the second equation.
