Question

Resolver para x
5x - 12 = 43

Answer 1

x=11

Explanation:

you need to group like terms together and -12 and 43 are like terms ...when transposing (moving) -12 to the other side of the equal sign ,the minus sign on -12 changes to a plus , because the additive inverse is subtraction

so 5x - 12 = 43

5x - 12 + 12 = 43 + 12 (what you do on the left hand side you also do on the right hand side )

5x + 0 = 55

5x = 55

dive both sides by 5 so that you'll be left with x because the question wants x not 5x

5x ÷ 5 = 55 ÷ 5

x = 11

Answer 2

Given:-

• 
  `\bold{ \mathfrak{5x - 12 = 43}}`

`\:`

Solution:-

`\frak{ \red↣ \: 5x - 12 = 43}`

`\:`

`\frak{ \red↣ \: 5x = 43 + 12}`

`\:`

`\frak{ \red↣ \: 5x = 55}`

`\:`

`\frak{ \red↣ \: x = \cancel (55)/(5) }`

`\:`

`\boxed{ \frak{ \red ↣ \: \purple{ x = 11 \: }}}`

`\:`

The value of x is 11.
