Question

Solve for x: 2x+4=8x+5

Answer 1

[|] Answer [|]

`\boxed{X \ = \ -(1)/(6)}`

[|] Explanation [|]

2x + 4 = 8x + 5

==========

Subtract 4 From Both Sides:

2x + 4 - 4 = 8x + 5 - 4

Simplify:

2x = 8x + 1

Subtract 8x From Both Sides:

2x - 8x = 8x + 1 - 8x

Simplify:

-6x = 1

Divide Both Sides By -6:

`(-6x)/(-6) \ = \ (1)/(-6)`

Simplify:

`X \ = \ -(1)/(6)`

`\boxed] \ Eclipsed \ [`

Answer 2

Subtract 2x from both sides

4 = 8x + 5 - 2x

Simplify 8x + 5 - 2x to 6x + 5

4 = 6x + 5

Subtract 5 from both sides

4 - 5 = 6x

Simplify 4 - 5 to - 1

-1 = 6x

Divide both sides by 6

-1/6 = x

Switch sides

x = -1/6
