(Btw, I did not copy anyone, so please do not say I did. Also, I am the first answer..)
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.
