Set up a system of equations.
X+y=6
Y-x =40
Substitution method.
Y=6-x
(6-x)-x =40
6-2x=40
-2x=34
X= -17
Plug it back into the equation.
-17+y=6
Y=33
(-17,33) is one of the possible answers.
-149 would be your answer
Answer:
yes 2=138 degrees
Step-by-step explanation:
Not hundo perecent sure, sorry if it's wrong, if you want me to show my work then please ask
One glass of milk has 11 carbs and one snack bar has 14 carbs.
Step-by-step explanation:
Let,
Glass of milk = x
Snack bar = y
According to given statement;
4x+2y=72 Eqn 1
2x+3y=64 Eqn 2
Multiplying Eqn 2 by 2

Subtracting Eqn 1 from Eqn 3

Dividing both sides by 4

Putting y=14 in Eqn 1

Dividing both sides by 4

One glass of milk has 11 carbs and one snack bar has 14 carbs.
