Answer 1

Answer:

x = 45

Explanation:

(x - 15) + (x - 15) + (x - 15) = 90

x - 15 + x - 15 + x - 15 = 90

3x - 45 = 90

3x = 90 + 45

3x = 135

3x/3 = 135/3

x = 45

Answer 2

Explanation:

90 minus 45 = 45, so it would be

45-15 | 45-15 | 45-15 = 90

45-15 is 30, so 30 times 3 is 90.

Therefore, X=45
