7 - 3x = 4Solve the following equations by systematic method

Question

`7 - 3x = 4`Solve the following equations by systematic method

Answer 1

Step-by-step explanation:

First, let us subtract 7 from both sides of the equation; this gives

`7-3x-7=4-7`
`\Rightarrow-3x=4-7`
`\Rightarrow-3x=-3`

Finally, dividing both sides by -3 gives

`-(3x)/(-3)=-(3)/(-3)`

`\Rightarrow x=-(3)/(-3)`
`\boxed{x=1.}`

Which is our answer!

Hence, the solution to the equation is x = 1.
