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
