1) x+y = 170
x-y = 26
2) Subtract the two equations from each other. Doing this you get 2y = 56.
So the value of y is 28. Then plug in the value of y into any of the two equations and solve for x.
x-28 = 26
x = 54
3) When writing solutions as an ordered pair, the x value always comes first followed by the y value. So it would be (54, 28).

![\boxed{\boxed{\sqrt[3]{d}\cdot \sqrt[3]{d}\cdot \sqrt[3]{d}=d}}](https://tex.z-dn.net/?f=%5Cboxed%7B%5Cboxed%7B%5Csqrt%5B3%5D%7Bd%7D%5Ccdot%20%5Csqrt%5B3%5D%7Bd%7D%5Ccdot%20%5Csqrt%5B3%5D%7Bd%7D%3Dd%7D%7D)
Step-by-step explanation:
The given expression is,
![=\sqrt[3]{d}\cdot \sqrt[3]{d}\cdot \sqrt[3]{d}](https://tex.z-dn.net/?f=%3D%5Csqrt%5B3%5D%7Bd%7D%5Ccdot%20%5Csqrt%5B3%5D%7Bd%7D%5Ccdot%20%5Csqrt%5B3%5D%7Bd%7D)
It can also be written as,
The exponent product rule of algebra states that, while multiplying two powers that have the same base, the exponents can be added.
As here all the terms have same base i.e d, so applying the rule
H + c = 605
c = h + 55
h + h + 55 = 605
2h + 55 = 605
2h = 605 - 55
2h = 550
h = 550/2
h = 275 <== there were 275 hamburgers sold on Friday
c = h + 55
c = 275 + 55
C = 330...there were 330 cheeseburgers sold on Friday

How to do integers operations?
Integers are whole numbers, both positive and negative. You can perform four basic math operations on them: addition, subtraction, multiplication, and division. When you add integers, remember that positive integers move you to the right on the number line and negative integers move you to the left on the number line
Cómo hacer operaciones con números enteros?
Los enteros son números enteros, tanto positivos como negativos. Puede realizar cuatro operaciones matemáticas básicas con ellos: suma, resta, multiplicación y división. Cuando sume números enteros, recuerde que los números enteros positivos lo mueven hacia la derecha en la recta numérica y los enteros negativos lo mueven hacia la izquierda en la recta numérica.
