7-2x=y
subsitute 7-2x for y
7-2x+2x=7
add like terms
7=7
true

y+2x=7

14-4x=2y

Solve 2x+y=7 for y

Add -2x to both sides

2x+y+-2x=7+-2x

y=-2x+7

Substitute -2x+7 for in -4x+14=2y

-4x=14=2y

-4x+14=2(-2x+7)

Simplify both sides of the equation

-4x+14=-4x+14

Add 4x to both sides

-4x+14+4x=-4x+14+4x

14=14

Add -14 to both sides

14+-14=14+-14

0=0

Infinitely many solutions

An ice cube is made of 5 fluid ounces of water. About how many milliliters of water does it take to make an ice cube
Sergio [31]

<u>ANSWER: </u>

147.868 mL of water is required to make an ice cube.

<u>SOLUTION: </u>

Given that, an ice cube is made up of 5 fluid ounces of water.

We need to find how many milli liters of water does it require to make an ice cube.

For, that we have to convert 5 fluid ounces in to units of milli liters.

We know that, 1 US fluid ounce equals to 29.5735 milli liters. i.e. 1 US fluid ounce = 29.5735 mL

Now,  

An ice cube is made by 5 fluid ounces = 5 x 1 fluid ounce

= 5 x 29.5735 mL  = 147.868 mL

Hence, 147.868 mL of water is required to make an ice cube.
