Hello :)
The answer is -8.4
Hope this helps and have a great day!
Answer:
B = -13
Step-by-step explanation:
Add 13 to both sides
- 13 = b
Substitute 5 and -5 into the equation and solve.
3x +5x = 8x
3(5) + 5(5) = 8(5)
15 + 25 = 40
40 = 40 (True)
3(-5) + 5(-5) = 8(-5)
-15 + (-25) = -40
-40 = -40 (True)
C is the correct answer.
Sorry the easiest way is
8x = 8x and plug in 5 and (-5). Its the same but takes away some addition.
