a) 2 (5x-3) = 24

= 10x -6 = 24

= 10x = 24+6

= 10x = 30

= x= 30/10

$\boxed{\sf{x = 3}}$

b) 5 (2x+1) = 50

= 10x+5=50

= 10x = 50-5

= 10x = 45

= x = 45/10

$\boxed{\sf{x = 4.5}}$

c) (3x+4)/2=9.5

= (3x+4)/2=95/10

( On cross multiplication )

= 10(3x+4) = 2×95

= 30x+40=190

= 30x=190-40

= 30x=150

= x=150/30

(on simplification)

$\boxed{\sf{x = 5}}$

d) (7+2x)/3=5

(On cross multiplication)

= 1(7+2x)=5(3)

= 7+2x=15

= 2x=15-7

= 2x=8

= x=8/2

(on dividing)

$\boxed{\sf{x = 4}}$
