Question

-8 = 5x- x + 12 - 8
solve for x

Answer 1

Explanation:

-8=5x-x+12- 8 we have to solve the equation.

`\sf \implies - 8=5x-x+12- 8`

We have to combine number which do not have variables like + 12 and -8. we have to see these two numbers to left hand side and when we shift these two number left hand side the sign of these two number are also change.

`\sf \implies - 8 - 12 + 8 = 5x - x`

Now, we have to Solve this. -8-12 = -20. We add these two numbers - 8 and -12 because - and - turns into + but. Now, we add this two numbers we get - 20. -20 + 8 = -12. We we get our answer that is -12 because minus and plus turns into minus.

`\sf \implies - 12 = 4x`

We write 4x because we subtract 5x with x here single x means 1x. So, 5x - 1x we get 4x.

`\sf \implies \cancel{ ( - 12)/(4) }= x`

`\sf \implies ( - 3)/(1) = x`

`\sf \implies - 3 = x`
