Answer:
-2.41
Explanation:
rearrange:
12x + 10 + 5x + 31
Or
12x + 5x + 10 + 31
Simplify and set that is = to zero so we can isolate x
17x + 41 = 0
To solve for x, we can isolate x on one side of the equation by subtracting 41 from both sides:
17x = -41
Finally, we can solve for x by dividing both sides by 17:
x = -41/17
therefore, x is equal to approximately -2.41 when we plug it back into the original equation:
12x + 10 + 5x + 31 = 0
12(-2.41) + 10 + 5(-2.41) + 31 = 0
-28.92 + 10 - 12.05 + 31 = 0
0 (which is true)
