Question

35x-13x=x-1
I don’t know

Answer 1

x =
`-(1)/(21)`

Explanation:

In an equation our aim is to find the value of what we are looking for as well as keeping the equation balanced. For example if we took away 13 only from one side then the equation would change so it's an important rule to keep in mind when solving equations, that you need to keep both sides of the equation the same.

35x - 13x = x - 1

→ Simplify

22x = x - 1

→ Minus x from both sides to isolate -1

21x = -1

→ Divide both sides by 21 to isolate x

x =
`-(1)/(21)`
