Identity property. Anything multiplied by 1 will give an answer identical to the operand.
If you mean: 5(x-4) = 5x-20 then both expressions are equivalent
[5x+13]
5x + 4 = 10x - 5 10x - 5x = 4 + 5 5x = 9 x = 1.8
If y equals 5x-15 and x equals 1 then the value of y comes out to be -10. So y equals 5x-15 is -10.
