5(2n-7)= 2n- 3
Use the distributive property to multiply 5 by 2n-7.
10n-35 =2n - 3
Subtract 2 from both sides.
10n-35-2n= -3
Combine 10n and -2n to get 8n.
8n - 35 = -3
8n= -3+35
Add -3 and 35 to get 32.
8n= 32
Devide both sides by 8
n= 32/8
n= 4
so Sam got mistaken from the beginning when he multiplied 5 and 7 he wrote 12 instead of 35.
