Ex 4.4, 1 Set up equations and solve them to find the unknown numbers in the following cases: (b) One-fifth of a number minus 4 gives 3. Let the number = n Given that, One βfifth of n minus 4 = 3 So, π/5 β 4 = 3 π/5 = 3 + 4 π/5 = 7 Let the number = n Given that, One βfifth of n minus 4 = 3 So, π/5 β 4 = 3 π/5 = 3 + 4 π/5 = 7 Let the number = n Given that, One βfifth of n minus 4 = 3 So, π/5 β 4 = 3 π/5 = 3 + 4 π/5 = 7 n = 7 Γ 5 n = 35
