8X + 1 = 12X - 3
4 = 4X
X = 1
Thirty decreased by three times a number is six less than three times the number. Find the number.
It is 5n - 8 <= 2n + 10
That depends on what the number is which you are decreasing by. It is a number less than or equal to 12. Beyond that nothing more can be said without further information.

Expressed algebraically, this is equal to 3x + 7.
4/7
Expressed algebraically, this is equal to 3x + 8=y.
2 x = 8 + 4x
5x+30=7x 7x-5x=-30 2x=-30 x=-15
No. Since the square root of a number is whatever number times itself will equal the given number, there can be only one.
It is: 3x = 2x+8 and the value of x is 8
