Step-by-step explanation:
I'm not sure if this is 100% right this question was kinda messing with my brain , but if it's like asking how much she had in the 4 games all you had to do was add 9+9+9+9 or to make it easier you can just multiply 9 times 4 but I hope this is right.
Answer:
To decide whether to add or subtract, determine if the values of the coefficients are the same or opposites:
. If the values are the same, subtract the equations.
• If the values are opposites or additive inverses, add the equations.
Step-by-step explanation:
Given
Required
How to solve
Options (1) and (2) are incorrect because none of the options eliminate x or y.
For option (3),
- Check for the coefficients of x and y
- If they are the same (sign and value), then subtract; otherwise add
For instance:
Rewrite the second equation
The coefficient of y are the same, so we subtract;
<em>See that y has been eliminated</em>
Based on the expression given in the image and the values of a, b, and c, the value of the expression is 6 ¹/₆.
<h3>How can you find the expression's value?</h3>
When given the values of a, b, and c, the value of the expression can be solved by plugging the digits into the expression.
The expression is:
= (a + 2bc) / 3a
Getting the value by solving gives:
= (4 + (2 x -5 x -7)) / (3 x 4)
= (4 + 70) / 12
= 74 / 12
= 6 ² /₁₂
= 6 ¹/₆
In conclusion, the value of the expression is 6 ¹/₆.
