Exercise 11 Page 85

To solve the equation, we have to isolate n on one of the sides. By subtracting 27 from both sides, we can cancel out 27 on the left-hand side and isolate n.

27+n=46

SubEqn

LHS-27=RHS-27

27+n-27=46-27

RearrangeEqn

Rearrange equation

n+27-27=46-27

SubTerms

Subtract terms

n=19

Therefore, n=19 is the solution to the equation. We can check our answer by substituting n=19 into the original equation and simplifying.

27+n=46

Substitute

n= 19

27+ 19? =46

AddTerms

Add terms

46=46

Since both sides are equal, n=19 is the correct solution.
