Which value is a solution of the equation 3 - 2x = -5?
A. 2
B. 4
C. -2
D. 1/5
B:4 is your answer
To find which value is a solution of the equation 3 - 2x = -5, we need to substitute each option into the equation and see which one makes the equation true.
Let's start with option A: 2. Substitute x = 2 into the equation:
3 - 2(2) = -5
3 - 4 = -5
-1 = -5
Since -1 is not equal to -5, option A is not a solution to the equation.
Now let's move on to option B: 4. Substitute x = 4 into the equation:
3 - 2(4) = -5
3 - 8 = -5
-5 = -5
Since -5 is equal to -5, option B is a solution to the equation.
Next is option C: -2. Substitute x = -2 into the equation:
3 - 2(-2) = -5
3 + 4 = -5
7 = -5
Since 7 is not equal to -5, option C is not a solution to the equation.
Finally, option D: 1/5. Substitute x = 1/5 into the equation:
3 - 2(1/5) = -5
3 - 2/5 = -5
15/5 - 2/5 = -5
13/5 = -5
Since 13/5 is not equal to -5, option D is not a solution to the equation.
Therefore, the solution to the equation 3 - 2x = -5 is option B: 4.
