4x + 1 = 2x - 2
Subtract 2x from each side: 2x + 1 = -2
Subtract 1 from each side: 2x = -3
Divide each side by 2: x = -1.5
Alternatively 4x + 1 = 2 - 2x which simplifies to 6x = 1, making x = 1/6.
The difference between a number x and twice y is equal to fifteen.

Three times the difference of a and m divided by twice their sum is equal to 6(a squared - m squared). 3(a - m)/2(a + m)
It is: 3x = 2x+8 and the value of x is 8
twice the difference of three times a number and eight
2x - 16 = 3x/18
The difference between a number x and twice y is equal to fifteen.
The difference between five times a number and twice that number can be expressed mathematically. If we let the number be represented by ( x ), then five times the number is ( 5x ) and twice that number is ( 2x ). The difference is calculated as ( 5x - 2x ), which simplifies to ( 3x ). Thus, the difference is three times the original number.

2*(x + 21) = 3*abs(x - 5) => x = -5.4 or x = 57.

It is 3*n - 5
2(x - 7) = 8
