Question

Solve: 3,125 = 5–10 + 3x

Answer 1

`3125=5-10+3x\quad :\quad x=(3130)/(3)\quad \left(\mathrm{Decimal}:\quad x=1043.33333\dots \right)`

Explanation:

`3125=5-10+3x`

`\mathrm{Switch\:sides}`

`5-10+3x=3125`

`\mathrm{Subtract\:the\:numbers:}\:5-10=-5`

`3x-5=3125`

`\mathrm{Add\:}5\mathrm{\:to\:both\:sides}`

`3x-5+5=3125+5`

`\mathrm{Simplify}`

`3x=3130`

`\mathrm{Divide\:both\:sides\:by\:}3`

`(3x)/(3)=(3130)/(3)`

`\mathrm{Simplify}`

`x=(3130)/(3)`

Answer 2

Answer: x = 3130/3 = 1043.333

Step-by-step explanation: Solve : -3x+3130 = 0

Subtract 3130 from both sides of the equation :

-3x = -3130

Multiply both sides of the equation by (-1) : 3x = 3130

Divide both sides of the equation by 3:

x = 3130/3 = 1043.333
