Question

Variable a is 4 more than variable b. Variable a is also 1 less than b. Which of the following pairs of equations best models the relationship between a and b?

a = b + 4
a = b − 1
a = 4b
a = b + 1
b = a + 4
b = a − 1
b = 4a
b = a + 1

Answer 1

1 . a = b + 4
a = b − 1

2. a = 4b
a = b + 1

3. b = a + 4
b = a − 1

4. b = 4a
b = a + 1
