Answer: x=-7

Step-by-step explanation:

-30=5(x+1)

multiply the brackets

-30=5x+5

take away 5x from both sides of the equation

-30-5x=5

add 30 to both sides

-5x=35

divide both sides by -5

x=-7

if eight times a number is increased by 3 the result is 19 more than six times this digit. find the number

Verdich [7]

Answer:

Step-by-step explanation:

Even though we don't know the number yet, let's name this number "n".

8n + 3 = 6n + 19

8n + 3 - 6n = 6n + 19 - 6n

2n + 3 = 19

2n = 16

n = 16/2

n = 8

Our number is 8.

Note: This answer is 100% correct.
