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.
A + 2a = 3a

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

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