Which of the following pairs of equations has exactly the same solution?
z/3.2 = 1.8 and 1.8x = 3.2
- 3/4 * x = 5/2 and 5/2 * x = - 3/4
- 3.2x = 0.64 and x/4 = - 0.05
3/8 * x = 1 and 1/3 * x = 1/8
The pairs of equations that have exactly the same solution are:
- 3/4 * x = 5/2 and 5/2 * x = - 3/4
These equations can be simplified to:
- (3/4) * x = 5/2 and (2/5) * x = - 3/4
Their solutions are x = 10/3 and x = -2/3 respectively. Both equations have the same solution x = 10/3 or -2/3.
