Write equations for the following statements:

(i) The sum of numbers x and 4 is 9.


(ii) 2 subtracted from y is 8.


(iii) Ten times a is 70.


(iv) The number b divided by 5 gives 6.


(v) Three-fourth of t is 15.


(vi) Seven times m plus 7 gets you 77.


(vii) One-fourth of a number x minus 4 gives 4.


(viii) If you take away 6 from 6 times y, you get 60.


(ix) If you add 3 to one-third of z, you get 30.


The parts of the questions are solved below:


i) According to the question, the sum of numbers x and 4 is 9.


Thus, we can write the equation as,


x + 4 = 9


ii) According to the question, 2 subtracted from y is 8.


Thus, we can write the equation as


y – 2 = 8


iii) According to the question, Ten times a is 70.


Thus, we can write the equation as,


10a = 70


iv) According to the question, The number b divided by 5 gives 6.


Thus, we can write the equation as,



v) According to the question, Three-fourth of t is 15.


Thus, we can write the equation as,



vi) According to the question, Seven times m plus 7 gets you 77.


Thus, we can write the equation as,


7m+ 7 = 77


vii) According to the question, One-fourth of a number x minus 4 gives 4.


Thus, we can write the equation as,



viii) According to the question, If you take away 6 from 6 times y, you get 60.


Thus, we can write the equation as,
