Each pair of equations below is equivalent. What was done to the first to get the second; in other words something was done to both sides of the first equation to "turn it into" the second equation - what was done to the first equation?
Any help would be very much appreciated.
there are no equations
I know, that's what had me confused as well. On my paper there aren't any equations to be shown.
To determine what was done to the first equation to obtain the second equation, we need to closely examine the similarities and differences between the two equations. Here's an example with two equations:
Equation 1: 2x + 5 = 15
Equation 2: 2x = 10
We can observe that the numbers on both sides of the equal sign have changed in Equation 2. In Equation 1, we have 5 on the right side, while in Equation 2, we have 0. To transform Equation 1 into Equation 2, we can subtract 5 from both sides of the equation.
By subtracting 5 from Equation 1, we have:
(2x + 5) - 5 = 15 - 5
Simplifying the expression:
2x = 10
Therefore, to turn Equation 1 into Equation 2, we subtracted 5 from both sides of the equation.
Keep in mind that this is just one example, and the specific operations required to transform the equations may vary depending on the given pair of equations.
