True or false the number 0 is the multiplicative identity ?

The multiplicative identity is a number that when you multiply by it, it does not change what you multiplied.

1 * 78 = 78
1 * 7 = 7
1 * (-9) = -9

Everything you multiply by 1 remains the same.
1 is the multiplicative identity.

Any number you multiply by 0 gives an answer of zero, not the original number, so zero is not the multiplicative identity.

use the subtraction property of equality to subtract 3x from both sides of the equation

Step-by-step explanation:

y is on the left so move everything else to the right side
