We can just plug in the values of x = 2 and y = 4 into the expression 4x+y to get 4*2 + 4 = 8 + 4 = 12.
for 2y-x = 2*4 - 2 = 8 - 2 = 6
Answer:
39 and 19
Step-by-step explanation:
sum: a+b=58
larger: a-b=20
(a+b)-(a-b)=58-20
2b=38 --> b = 19, a=39

Rememember you can do anything to an equation as long as you do it to boht sides except diviede by zero and when you mulitply by a negative with inequalities (<u><</u>, <,<u>></u>,>) remember to flip the sign
sum means add
twice a number means a number times 2 (represented by x)
greater than means >
3 times means multiply
minus is minus
so
sum of twice a number and 5 (2x+5) is greater than (>) 3 times the number (3x) minus 3 (-3)
we now have
2x+5>3x-3
subtract 2x from both sides
5>x-3
add 3 to both sides
8>x
x<8
therefor x is any number less than 8
x can be 7,6,5,4,3,2,1,0,-123189030, π
basically x<8
