Question

Which value is the solution to the equation 2b + 5b - 7 = 14. When the replacement set is {2, 3, 4, 5}?

Answer 1

2.25

Explanation:

2b + 2b - 4=5

Add 2b + 2b

bring down the -4 and 5

4b - 4=5

4b= 5+4

Add 5 + 4=9

4÷4b=9÷4 -Divide n both side

cancel the 4 sense their the same and bring down the B

Divide 9 and 4

9÷ 4= 2.25

B=2.25
