Exercise 10 Page 85

To solve the equation we need to isolate x on one side of the equation. By subtracting 2 from both sides, we can cancel it from the right-hand side.

6=x+2

SubEqn

LHS-2=RHS-2

6-2=x+2-2

4=x

RearrangeEqn

Rearrange equation

x=4

Therefore, x=4 is the solution to the equation. To check that we have the correct solution, we can substitute x=4 into the original equation and simplify.

6=x+2

Substitute

x= 2

6? = 4+2

Add terms

6=6

Since the left-hand side and right-hand side are equal, x=4 is a correct solution.
