-84.8 is with it rounded to the nearest tenth
Answer:
10
Step-by-step explanation:
The number is 1/6. 15 minus 3 = 12. 12 times 1/6 is 2
8y = 4x -16
-x = -2y -4
Multiply all terms in the second equation by -1:
-x = -2y -4 x -1 = x = 2y +4
Now replace x in the first equation with this.
8y = 4(2y+4)
Simplify:
8y = 8y +16
Because there is an 8y on both sides of the equation, it cannot be solved.
The answer is no solution.
A letter, which is how you name it. If that is what your asking, of course.
