Q.23 Solve the following equations and check the aanswer
5z+1/3=7

Answer 1

Answer:

z = 4/3

Step-by-step explanation:

5z + 1/3 = 7

5z = 7 - 1/3

5z = (21-1)/3

z = (20/3) × (1/5)

z = 4/3

Check:      5z + 1/3 = 7

                 5 × (4/3) + (1/3) = 7

                 20/3 + 1/3 = 7

                 21/3 = 7

                 7 = 7
