Answer: When x=2 and z = 1, then the value of y =4.
Step-by-step explanation:
Given: y varies directly as x and z i.e. 
(i) , where k is the proportionality constant.
Put Y=40 ,x =5 and z = 4, then we get

Required equation:
[Put value of k in (i)]
Now put x=2 and z = 1, then we get

Hence, when x=2 and z = 1, then the value of y =4.
Answer:
x = -1
Step-by-step explanation:
3(x+2)=−5−2(x−3) multiply 3 and -2 with inside the parenthesis
3x + 6 = -5 -2x + 6 now add the like terms
3x + 2x = 1 - 6
5x = -5 simplify both sides
x = -1
