Question

8x+7/5x+9 =0. please show me the verification​

Answer 1

Hello !!

We have a equation of first degree and we have find the solution for the unknown (x) and show the verification.

8x + 7/5x + 9 = 0

8x/1 + (7/5)x + 9 = 0

(40x + 7x)/5 + 9 = 0

47x/5 + 9 = 0

47x/5 + 9/1 = 0

(47x + 45)/5 = 0

(47x + 45) = 0 × 5

(47x + 45) = 0

47x + 45 = 0

47x = 0 - 45

47x = -45

x = -45/47

Now , we show the verification.

8x + 7/5x + 9 = 0

8(-45/47) + 7/5(-45/47) + 9 = 0

0 = 0 (TRUE)

Final result :

The solution for (x) is -45/47.

I hope I have collaborated and have a great day !
