Answer:
x=1, y=-1. (1, -1).
Step-by-step explanation:
2x+y=1
3x-y=4
-------------
y=3x-4
2x+3x-4=1
5x-4=1
5x=1+4
5x=5
x=5/5
x=1
y=3(1)-4=3-4=-1
B) 7 would make it true, since both 42/54 and 7/9= 0.77 repeating
x ≤ 12
Solution:
Let us take the number be x.
A number : x
A number divided by three :
A number divided by three less two :
A number divided by three less two is at most two :
Now, simplify the inequality,
Add 2 on both sides of the inequality,
Multiply by 3 on both sides of the equation,
Hence x ≤ 12.
The equation in standard form would be,
All you have to do is move -2/7x to the other side.
