Answer:

D. 2

Step-by-step explanation:

We know that y=2x-3. We want to find out what the value of x is when y=1. Therefore, we can substitute 1 in for y in the equation.

Equation: y=2x-3

Substitute 1 in for y: 1=2x-3

Now, solve for x.

1=2x-3

3 is being subtracted from 2x. The inverse of subtraction is addition. Add 2 to both sides.

1+3=2x-3+3

1+3=2x

4=2x

x is being multiplied by 2. The inverse of multiplication is division. Divide both sides by 2.

4/2=2x/2

4/2=x

2=x

The correct answer is D. 2
