<em><u>Question:</u></em>
4x + 2y = 0
- 4x – 9y= - 28
Solve each system by elimination
<em><u>Answer:</u></em>
The solution is x = -2 and y = 4
<em><u>Solution:</u></em>
<em><u>Given system of equations are:</u></em>
4x + 2y = 0 ------ eqn 1
-4x – 9y = - 28 ------- eqn 2
We have to solve the system of equations by elimination method
Add eqn 1 and eqn 2
4x + 2y -4x -9y = 0 - 28
0 + 2y - 9y = -28
-7y = -28
Divide both sides by -7
y = 4
<em><u>Substitute y = 4 in eqn 1</u></em>
4x + 2(4) = 0
4x + 8 = 0
4x = -8
Divide both sides by 4
x = -2
Thus the solution is x = -2 and y = 4

Answer: 1/2x + 1/3
Step-by-step explanation:
Given:
1/4(x) + 3/4(x) - 1/2(x) + 1 - 2/3
Step 1: Combine like terms
1/4(x) and 3/4(x) have a common denominator of 4. This means that you can add them together.
1/4(x) + 3/4(x) = 4/4(x) = x
Step 2: Find the common denominator of x in step 1 and combine like terms
x - 1/2(x) = 2/2(x) - 1/2(x)
Now that we have the common denominator of x, we can combine like terms. Its the same as adding or subtracting fractions without a variable. In this case, you must subtract 1/2(x) from 2/2(x).
2/2(x) - 1/2(x) = 1/2(x)
Step 3: Find the common denominator of the constants and combine like terms
1 - 2/3 = 3/3 - 2/3
Now combine like terms. Simply subtract 2/3 from 3/3.
3/3 - 2/3 = 1/3
Step 4: Write the simplified equation
1/2(x) + 1/3
This is the answer
