7n-4=31
7n=31-4
7n=27
n=27/7
:n=3
It’s equation and it’s really easy to solve
Answer:
Answer
2x+3y=14,2x−3y=2
Adding :
2x+3y=14
2x−3y=2
__________
4x=16
x=4
∴xy=4×2
=8
2×4+3y=14
8+3y=14
3y=6
y=2
Step-by-step explanation:
here you go
Answer:
X=11
Step-by-step explanation:
9x+6= (3x+2)+(70)
Simplify: 6x+6=72
6x+6=72
6x=66
x=11
E(w,0) the kite has one pair of equal opposite sides
One is 1/2 and 2/4 because when you simplify it is 1/2 I think that's the answer but I know that 2/4 in simplify form is 1/2
