<em><u>Option B</u></em>
The result of addition is 2y = 24
<em><u>Solution:</u></em>
Given that we have to add the equations
<em><u>Given equations are:</u></em>
5x - y = -1
-5x + 3y = 25
We have to add both equations
This is similar to adding numbers. i,e 1 + 2 = 3
<em><u>For adding variables,</u></em>
When adding or subtracting terms that have exactly the same variables, you either add or subtract the coefficients, and let the result stand with the variable.
Example: 2x + 3x = 5x
Keeping this in mind, let us add the given equations
5x - y = -1
-5x + 3y = 25
----------------------------
0 + 2y = -1 + 25
[ 5x and -5x cancels each other. Combine -y and 3y which gives 2y]
2y = 24
Thus Option B is correct
Kiran can explain factoring to lin by finding what multiples together to get an expression. It is in a way, like splitting an expression into multiplication easier expressions.
Answer:
the answer should be (1,6)
You only need to flip the inequality if you multiply or divide the inequality by a negative number.
-3t + 7 ≥ 9
Subtract both sides by 7.
-3t + 7 - 7 ≥ 9 - 7
-3t ≥ 2
Divide both sides by -3.
-3t / -3 ≥ 2 / -3
t ≤ 2/-3
So, yes, you will need to flip around the inequality sign.
