Answer:
x = 7
Step-by-step explanation:
Let
x = the unknown number
double it :
2x
add 11:
2x + 11
I get 25:
The equation is
2x + 11 = 25
2x = 25 - 12
2x = 14
Divide both sides by 2
x = 14/2
0.0608365019
..............
5
9x+6y=-3
9x+6(-8)=-3
9x-48=-3
9x=45
x=5
m=3
b=(0,5)
the answer is the 2nd one from my point of view u will understand so the solution set for the quality is the 2nd answer either way or
x= +2, -2
hope it helps you
