x=6=x=5+x=13+x=20 x cannot = x+5. This question has no answer.
9 x 20 = 180
x+3 = 20 x = 20-3 x = 17

x2 - x = 20 x = 5
To find what equals 16 when added to 20, you can set up the equation: 20 + x = 16. Solving for x, you subtract 20 from both sides, yielding x = 16 - 20, which simplifies to x = -4. Therefore, 20 plus -4 equals 16.
x-14 = 20 x = 20+14 x = 34
It is an equation and the value of x is 20
x = 20
34
3x+5=20 x=5 since 5x3+5=20
