Answer:
see explanation
Step-by-step explanation:
15 less than 3 times n is 3n - 15, thus
n + 3n - 15 = 101 ← equation modelling the situation
4n - 15 = 101 ( add 15 to both sides )
4n = 116 ( divide both sides by 4 )
n = 29
Answer:
Step-by-step explanation:
y = 5x + 4
-5x + y = 4 ----------------------(i)
3x + 2y = 20 --------------------(ii)
Multiply equation (i) by (-2)
(i)* (-2) 10x - 2y = -8
(ii) <u>3x + 2y = 20</u> { Now add this two equations}
13x = 12 { -2y and 2y got eliminated}
x = 12/13
Plug in value of x in (i)
-5*12/13 + y = 4
-60/13 + y = 4
y = 4 + 60/13
