Answer:
A) 5x² - 6x + 1
Step-by-step explanation:
In this question, you would have to simplify the expression.
Solve:
(3x² - 2) + (2x² - 6x + 3)
Combine like terms.
3x² - 2 + 2x² - 6x + 3)
5x² - 2 - 6x + 3
5x² - 6x + 1
Since there's no more like terms, we have completely simplified the expression.
Therefore, your answer would be A) 5x² - 6x + 1
Answer:
x+3y = 6
or, x = 6-3y.................(1)
3x+5y =6..........(2)
Substituting x = 6-3y in equation (2),
3 (6 - 3 y)+5 y =6
or, 18 - 9y +5y=6
or, y = 3
x = 6 - 3y = 6- 3.-3 = -3
