Solving Systems of Equations by Substitution Worksheet for 8th ... - Free Printable

It looks like you've uploaded a worksheet titled "Solving Systems of Equations by Substitution", which contains several systems of linear equations to solve using the substitution method.

Since I can't view images directly, I'll need you to describe or type out the specific problem(s) you'd like help with. However, I can explain how to solve such problems in general and walk through an example.

🔧 How to Solve a System of Equations by Substitution

Steps:

1. Solve one equation for one variable (usually isolate one variable).
2. Substitute that expression into the other equation.
3. Solve the resulting equation for the remaining variable.
4. Plug back to find the value of the first variable.
5. Write the solution as an ordered pair (x, y).

✔ Example Problem (from typical worksheets):

Let’s assume one of the problems is:

> 1)
> $ x + y = 6 $
> $ 2x - y = 3 $

#### Step 1: Solve one equation for one variable

From the first equation:
$$
x + y = 6 \Rightarrow x = 6 - y
$$

#### Step 2: Substitute into the second equation

Replace $ x $ in the second equation:
$$
2(6 - y) - y = 3
$$

#### Step 3: Solve for $ y $
$$
12 - 2y - y = 3 \\
12 - 3y = 3 \\
-3y = -9 \\
y = 3
$$

#### Step 4: Plug back to find $ x $
$$
x = 6 - y = 6 - 3 = 3
$$

#### Step 5: Solution
$$
(x, y) = (3, 3)
$$
