Solve the system of equations. 14x + y = −4 y = 3x^2 − 11x − 4

sveta [45]

You can use substitution here. First, get y alone:

14x + y = -4
subtract 14x from each side
y = -4 - 14x

Then, plug y into the second equation

-4 - 14x = 3x² - 11x - 4
then solve from there

Hope this helps :)

5 5 I think of a number, treble it then add on 3, the result is equal to 6. Find the value of the original number I thought of.

Licemer1 [7]

Let the number be x

If 3 is added to tripple the number then the result is 6

$\\ \sf\longmapsto 3x+3=6$

$\\ \sf\longmapsto 3x=6-3$

$\\ \sf\longmapsto 3x=3$

$\\ \sf\longmapsto x=1$
