Sh = 2Ni + 2
St = 5Ni -10
Sh + Ni = St
(2Ni + 2) + Ni = 5Ni - 10
Solve for Ni.
Read the above data out loud to get the verbal model.
St = 5Ni -10
Sh + Ni = St
(2Ni + 2) + Ni = 5Ni - 10
Solve for Ni.
Read the above data out loud to get the verbal model.
It could be any numbers
S=2x+2
N=x
St=(2x+2)+x
(2x+2)+x=5x-10
3x-5x=-10-2
-2x=-12
X=6
Then substitute to S and St to get their age
N=x
St=(2x+2)+x
(2x+2)+x=5x-10
3x-5x=-10-2
-2x=-12
X=6
Then substitute to S and St to get their age
