Question

x+x+20+x+37=180
=> x+x+x=180-20-37
=>3x=123
=>x=123/10
=x=41

Therefore, 41, 41+20, 41+37
=41, 61, 78


IS MY CALCULATION CORRECT

Answer 1

Ya Absolutely right..

Answer 2

x + x + 20 +x +37=180
3x +57=180
3x =180- 57
3x=123
x=123/3
x =41

Therefore, 41, 41+20, 41+37
=41, 61, 78.
Your calculations is correct, but, something is wrong, in the step four.

Here it is,
3x=123
x=123/10.this is wrong, but u wrote the correct answer, still.
