1 + (-5) becomes 1 - 5 because you are adding a negative number.
1 - 5 is -4
Is there supposed to be parentheses?
X=skirt
y=sweater
z=shoes
x+y+z=165
y=8/7x
z=x+11
plug it in
x+(8/7x)+(x+11)=165
2x+8/7x=154
22/7x=154
x=49
y=56
z=60
a skirt cost $49, a sweater cost $56, and a pair of shoes cost $60
Hope this helps, have a great!!
