find the value of base x

9514 1404 393

  x = 6

Step-by-step explanation:

The place values of the digits from left to right are b^2, b, 1.

The units digits have a sum of 9, but that is represented in these numbers by a units digit of 3 and a "b" digit of 1.

  9 will be represented by b +3 when b = 6

The base of these numbers is 6.

Additional comment

Translated to decimal, the sum is 207 = 100 + 107.

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
