In a sequence of numbers, each number is 7 less than 3 times the previous number. For example, if the first number is five, the second number would be 8 (3 x 5 - 7) and the third number would be 17 (3 x 8 - 7). If the third number in the sequence was 53, what was the first number in the sequence?

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
