Answer:
The correct answer is A. x = - 9
Step-by-step explanation:
Let's solve the equation:
5x + 8 − 3x = −10
5x - 3x = - 10 - 8
2x = - 18
x = - 9 (Dividing by 2 at both sides of the equation)
Now let's prove the answer is correct, replacing x with - 9.
5x + 8 − 3x = −10
5 (-9) + 8 - 3 (-9) = - 10
-45 +8 - 27 = - 10
-45 + 35 = - 10
-10 = - 10
It has proven the value of x = - 9 is correct
The correct answer is A. x = - 9
