The answer to subtracting x from 4 is 4 - x. This is because subtraction is the operation of finding the difference between two numbers, in this case 4 and x. When you subtract x from 4, you are taking away the value of x from 4, resulting in the expression 4 - x.
4+ X equals 2X. Subtract X from both sides. Four equals X
2x - 1 = 3x + 4 Subtract 2x from both sides: - 1 = x + 4 Subtract 4 from both sides: -5 = x
Subtract x so -4 = 2x/ x= -2
3x + 4 = 2x - 3 Subtract 2x from both sides: x + 4 = - 3 Subtract 4 from both sides: x = -7
