Answer:

1x+2=8+-1​

1+2=7

(x+2) + (-2) = 7 (-2)

x + 2-2=7-2

x=5

Step-by-step explanation:

  • Number 1 as a factor, does not need to be explicitly written.
  • In our example, the above transformation has been applied once.
  • In order to solve this linear equation, we need to group all the variable terms on one side, and all the constant terms on the other side of the equation.
  • In our example, term 2 , will be moved to the right side.
  • Notice that a term changes sign when it 'moves' from one side of the equation to the other.
  • We need to get rid of expression parentheses.
  • If there is a negative sign in front of it, each term within the expression changes sign.
  • Otherwise, the expression remains unchanged.
  • In our example, there are no negative expressions.
  • Numerical terms in this expression have been added.
