Question

7x − 12 = 5x + 17
what is x?

Answer 1

`x=14.5`

Explanation:

The given equation is :

`7x- 12 = 5x + 17`

Taking the terms of 'x' to one side and the constants terms to the other side.

Subtracting '
`5x`' both the sides

`7x-12-5x=5x+17-5x\\\\7x-5x-12=17\\\\2x-12=17`

Adding '12' both the sides

`2x-12+12=17+12\\\\2x=29\\\\x=29/2`

`x=14.5`

Answer 2

x = 14.5

Explanation:

Step 1: Subtract 5x from both sides

7x − 12 - 5x = 5x + 17 - 5x

2x - 12 = 17

Step 2: Add 12 to both sides

2x - 12 + 12 = 17 + 12

2x = 29

Step 3: Divide both sides by 2

2x / 2 = 29 / 2

x = 14.5

Answer: x = 14.5
