Answer 1

A.

$3x - 3 = 48$

here x is the age of the daughter.

B.

$5w + s = 48$

here w is the number of white beads.

C.

$m - s = 8 \\ m + s = 178$

here, m= marks in mathematics

and s= marks in science.

$b + g = 64 \\ b - g = 12$

here, b= number of boys in the class

and g= number of girls in the class.
