Question 6
If 7x + 4 = 25, then x is equal to
(a) 297
(b) 1007
(c) 2
(d) 3
Given equation is 7x + 4 = 25 ⇒7x=25−4⇒7x=21 On dividing the above equation by 7, we get x = 3 Hence, the solution of the given equation is 3.
Question 12
(−11)×7 is not equal to
(a) 11×(−7) (b) −(11×7) (c) (−11)×(−7) (d) 7×(−11)
Solve the following question to find the value of 'x': 7x+4=25+4x
If x+x=12, then value of x should be equal to
