Emma took a certain 100-point test twice. The points received on the test can be converted to a rating from according to the formula, R=1.4P+23, where R represents the rating and P represents the points received. How many more points did Emma receive on her second test compared to her first if her rating increased by 63? I do not need an answer, the correct answer is 45. I would like a formula to calculate this along with somewhat of an explanation.

my name is emma :)
R=1.4P+23 R2 - R1 = 63.. So, (1.4P2 + 23 ) - (1.4P1 + 23) = 63 1.4P2 -1.4P1 = 63 1.4 (P2 - P1 ) = 63 P2 -P1 = 45...
