2x -y =3; D:{-2,0,1,3}

y= 2x-3

Step-by-step explanation:

2x-y =3

-2x     -2x

-y= 3-2x

-y=-2x+3/-1

y=2x-3

the difference between a number and 5 is -2.

step-by-step explanation:

notice that the equation you are given has -2 (negative 2) on the right side, not 2. when you subtract 5 from a number n, you are finding the difference between the number and 5.

the difference between a number and 5 is -2.

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
