Question

20+3m-8=0 and then find the value of m

Answer 1

Answer:

20+3m-8=0

20-8=-3m

12=-3m

m=12÷-3

m=-4

Answer 2

Answer:

m = - 4

Step-by-step explanation:

20 + 3 m - 8 = 0

Here , we know that 20 + 3 m has to be 8 so only 8 - 8 = 0.

8 = 20 + 3 m

m = 8 - 20 / 3

m = - 12 / 3

m = - 4

Now , the equation is equal to

= 20 + 3 ( - 4 ) - 8 = 0

________

= 20 + ( - 12 ) - 8 = 0

____________

= 8 - 8 = 0
