Answer 1

3x+5x =232
8x=232
x=29

hope it helps you. . .

Answer 2

Let the two numbers be x and y
Given that x:y = 3:5
x/y = 3/5
5x = 3y
5x - 3y = 0 (equation 1 )

Sum of the numbers = 232
x + y = 232 (equation 2)

Taking 1 and 2 as simultaneous equations
5x - 3y = 0
x + y = 232

5x - 3y = 0
5x + 5y = 1160

subtracting 2 from 1

5x - 3y = 0
-5x - 5y = - 1160

- 8y = - 1160
y = 145

x + 145 = 232
x = 87

The numbers are 145 and 87.
