Solve it................​

Answer 1

Answer:

(1)5y=40

(2)Z+8=15

(3)25-a=7

(4)X-5=3

(5)3/5b=16

(6)q/12=24

Answer 2

Answer:

(i) Let the required number be x.

so five times the number will be 5x.

∴5x = 40

(ii) Let the required number be x.

so,when it is increased by 8,we get x+8

∴x+8 = 15

(iii) Let the required number be x.

so when 25 exceeds the number we get 25 - x

∴25 - x = 7

(iv) Let the required number be x

so when the number is exceeds 5, we get x - 5

∴x - 5 = 3

(v) Let the required number be x

so thrice the number be 3x

∴3x - 5 = 16

(vi) Let the required number be x

so 12 is subtracted from the number we get x - 12

∴x - 12 = 24

(vii) Let the required number be x

so twice the number will be 2x

∴19 - 2x = 11

(viii) Let the required number be x

$so \: the \: no. \: when \: div. \: by \: 8 \: will \: be \frac{x}{8}$

$\frac{x}{8} = 7$

(ix) Let the required number be x

so four times the no. will be 4x

∴4x - 3 = 17

(x) Let the required number be x

so six times the no. will be 6x

∴6x = x+5
