X can be either 1.33, 0.382, 0.053, or 0.094, we can solve each equation separately by dividing both sides of each equation by the coefficient of x.
To find x, we can look at the given equations:
15x = 20
17x = 6.5
19x = 1
21x = 1.97
We can solve each equation separately.
For the first equation, we divide both sides by 15: x = 20/15 = 1.33
For the second equation, we divide both sides by 17: x = 6.5/17 = 0.382
For the third equation, we divide both sides by 19: x = 1/19 = 0.053
For the fourth equation, we divide both sides by 21: x = 1.97/21 = 0.094
So x can be either 1.33, 0.382, 0.053, or 0.094.
