Question

divide 180 into two parts such that the first part is 12 less than twice the second part

Answer 1

X +(X-12)=180
2x-12=180
2x=180+12
2x=192
x=192\2
x=96

Answer 2

Let the two numbers be x and y.

Given that Divide 180 into 2 parts.

x + y = 180   --------------- (1)

Given that the first part is 12 less than twice the second part.

x = 2y - 12  ---------------- (2)


Substitute (2) in (1), we get

2y - 12 + y = 180

3y - 12 = 180

3y = 192

y = 64.


Substitute y = 64 in (1), we get

x + 64 = 180

x = 180 - 64

x = 116.


Therefore the two parts are 64 and 116.

Verification:

x + y = 180

64 + 116 = 180

180 = 180.


Hope this helps!
