Answer:
(-8,8)
Step-by-step explanation:
Simplify |n| + 4 < 12. To do this, subtract 4 from both sides. This results in:
|n| < 8. The solution set includes all real numbers between -8 and 8, but not -8 itself or 8 itself.
we have that
x + 3y = 6 -------> first equation
2x − y = 10
x + 3y = 6-----> substract x both sides
-x+x+3y=6-x
3y=6-x-----> divide by 3 both sides
y=(6-x) /3
y=2-(x/3)
y=-(x/3)+2
therefore
the answer is
negative one thirdx + 2
