Respuesta :
She bought 11 shirts and 4 pants
Let x= pants
Let y= shirts
x+y=15
x+7=y
x=y-7
(y-7)+y=15
2y=22
y=11
x+y=15
11+x=15
x=4
Therefore, Elaine bought 11 shirts and 4 pants

Answer:
11 shirts and 4 pants.
Step-by-step explanation:
Let x be the number of shirts and y be the number of pants,
So, the total shirts and pants = x + y
According to the question,
x + y = 15 ----(1),
Also, shirts are 7 more than pants,
i.e. x = y + 7
Substitute this value in equation (1),
y + 7 + y = 15
2y + 7 = 15
2y = 8
⇒ y = 4
Again from equation (1),
x + 4 = 15
⇒ x = 11
Hence, she bought 11 shirts and 4 pants.
