Exercise 5 Page 44

To solve the equation, we first have to isolate - b.

b=-5

Practice makes perfect

To solve the equation, we first have to isolate - b. We can do this by subtracting 1 from both sides.

6=1-b

▼

Rewrite 1-b as - b+1

6=- b+1

LHS-1=RHS-1

6-1=- b+1-1

Subtract terms

5=- b

LHS * (- 1)=RHS* (- 1)

-5=b

Rearrange equation

b=-5

Therefore, b=-5 is the solution to the equation. We can check our solution by substituting it into the original equation.

6=1-b

b= -5

6? =1-( -5)

a-(- b)=a+b

6? =1+5

Add terms

6=6 ✓

Since the left-hand side and right-hand side are equal, we know the solution is correct.
