Answer: y= -x-5
Step 1: Determine which equation to change
Since we will be using the substitution method, we will need to substitute y from the bottom equation with information from the top equation. This will be the equation we change.
Step 2: Change the equation
Let’s rewrite the equation we will be working with.
3x+3y= -15
Our goal will be to get y alone on the left side. To start, let’s subtract 3x from both sides, leaving only 3y on the left side.
3x+3y= -15
3y= -3x-15
Now we need to get y completely alone by eliminating the coefficient of 3. Let’s do this by dividing each term by 3.
3y= -3x-15
y= -x-5

The weeks will it take the grass to grow 12 over 7 centimeters is 3 weeks.
<h3>What is the unitary method?</h3>
The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
St. Augustine grass can grow at the rate of 4 over 7 centimeters per week.
The weeks will it take the grass to grow 12 over 7 centimeters
4/7 x = 12/ 7
28x = 84
x = 84/28
x = 3
The weeks will it take the grass to grow 12 over 7 centimeters is 3 weeks.
