Question

Solve the following equation
3x + 5 = 17

Geometry pre

Answer 1

`\boxed{ \boxed{ \bold{4}}}`

Explanation:

`\mathsf{3x + 5 = 17}`

Move constant to R.H.S and change it's sign

⇒
`\mathsf{3x = 17 - 5}`

Subtract 5 from 17

⇒
`\mathsf{3x = 12}`

Divide both sides of the equation by 3

⇒
`\mathsf{ (3x)/(3) = (12)/(3) }`

Calculate

⇒
`\mathsf{x = 4}`

Hope I helped!

Best regards!

Answer 2

x = 4

Explanation:

First, we need to get the 3x by itself on the left. To do this, we subtract 5 from both sides. 3x + 5 - 5 = 17 - 5; 3x = 12. Now, to find x, we divide both sides by 3 to get 3x/3=12/3; x = 4
