Question

Find the value of x. 7x+15=30

Answer 1

x= 15/7

hope it helps!

Explanation:

First state the equation:

7x+15=30

Bring 15 to the other side of the equation, making the (+) to (-)

So,

7x+15= 30

7x= 30-15

7x= 15

Bring 7 to the other side, it'll become 1/7

x= 15*1/7

= 15/7

= 2.14 in decimal form

Answer 2

Answer: x=2.1

Explanation:

`7x+15=30`

`-15` on both sides

7x=15

divide 7 on both sides

x=2.14

round

x=2.1
