Answer 1

Answer:

Step-by-step explanation:

for expression 5x-2=3x+4 to be equal

5x-2x=6

3x=6

x=2

the vale of x to be equal is 3

2) given that 2y=5y-12

5y-2y=12

3y=12

y=4

3)given that

let the share of A be a

the share of B be a-24

according to problem a+a-24=112

2a=112+24

2a=136

a=68

4)    c

7)
