Question

if 4(3x-8)= 25, what is 3x - 10?
​

Answer 1

Answer:

4(3x-8)=25

12x-32=25

12x=25+32

12x=56

x=56/12

x=23/6

3x-10

3(23/6)-10

23/2-10

23-20/10

3/10

Answer 2

4(3x-8)= 25

or, 3x-8 = 25/4

or, 3x-8-2= 25/4 -2 (substracting 2 both sides)

or, 3x-10 = 25/4 -2

or, 3x-10 = (25-8)/4

= 17/4
