Given the numerical equation:
2x - 7 = 19
Determine the solution.
Solution:
In order to determine the solution, we simply solve for x. To do so, transpose -7 on the other side of the equation, hence we must take note that in transposing a number, the sign changes.
2x - 7 = 19
2x = 19 + 7
2x= 26
Divde both sides of the equation by 2 in order to cancel out 2x.
2x/2 = 26/2
x = 13
Final answer:
x = 13
