Answer:

Step-by-step explanation:
In order to find r we have to square both sides of the equation

The *square root* sign cancels out the *squared* sign therefore:

2 hamburger + 1 milk =5
1 hamburger + 2 milk =5-.25
1 hamburger + 2 milk =4.75
multiply this by -2
-2hamburger + -4 milk =-9.5
add the first equation
-2 hamburger + -4 milk =-9.5
2 hamburger + 1 milk =5
---------------------------------------
-3 milk = -4.5
divide by -3
milk = 1.50
Answer: milk $1.50

Step-by-step explanation:
We just need to see everything that is not x as a number.
if I asked

we would solve it by combining like terms first. but, if I tell you not to do that, we would add 9 and 7(2) to both side and end up with

we would then divide both sides by 7

math is always math... it's just how we look at it. so, do the same steps!

add 9 and 7z to both side

divide both sides by 7
