Form equation from the following statement:
Three-fourths of a number x gives 15.
Forming equation:
Three-fourths of a number x=34ofx=34×x=3x4
Also, three-fourths of a number x gives 15.
⇒3x4=15
Thus, 3x4=15 is the required equation.
Question 4(iv) Write the equation for the following statement: One-fourth of a number x minus 4 gives 4.
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.
