Question

Solve the equation. 25=9x+4-6x

Answer 1

Explanation:

`25 = 9x + 4 - 6x`

`25 - 4 = 9x - 6x \\`

`21 = 3x`

`(21)/(3) = x`

`7 = x`

Answer 2

`\boxed{ \bold{ \huge{ \boxed{ \sf{x = 7}}}}}`

Explanation:

`\star{ \tt{ \: 25 = 9x + 4 - 6x}}`

`\sf{Step \: 1 \: }` : Collect like terms

Like terms are those which have same base

`\longmapsto{ \sf{25 = 3x + 4}}`

`\tt{Step \: 2 \: }` : Swap the sides of the equation

`\longmapsto{ \sf{3x + 4 = 25}}`

`\tt{Step \: 3 \: }` : Move 4 to right hand side and change it's sign

`\longmapsto{ \sf{3x = 25 - 4}}`

`\tt{Step \: 4}` : Subtract 4 from 25

`\longmapsto{ \sf{3x = 21}}`

`\tt{Step \: 5}` : Divide both sides by 3

`\longmapsto{ \sf{ (3x)/(3) = (21)/(3)}}`

`\tt{Step \: 6}` : Calculate

`\longmapsto{ \sf{x = 7}}`

The value of x is 7

Hope I helped!

Best regards! :D
