Example: Set up proportions.

3/4 cups → 1 batch
x cups → 2 batches

x = 2(3/4) = 6/4 = 1 1/2 cups

3/4 cups → 1 batch
y cups → 9 batches

y = 9(3/4) = 6 3/4 cups

Use the substitution method to determine the solution to the system of equations below. y-2x+2=1 6x - 3y = 3

vaieri [72.5K]

Answer:

y = 2x - 1

Step-by-step explanation:

y - 2x + 2 = 1

6x - 3y = 3

<u />

<u /> $y - 2x + 2 = 1 \\ +2x - 2 +2x - 2\\y = 2x - 1$

Plug in for y:

6x - 3(2x - 1) = 3

6x - 6x + 3 = 3

Simplified, 3 = 3
