Steps:
7w - 2 + w = 2(3w - 1)
6w - 2 = 6w - 2
Because both sides of the equation are equal, w = an infinite amount of solutions.
Have a great day!
The answer is 92 estimates 90
True I think I am not Fr Fr tho
sweater = s, blouse = b
s + b = 57, s = 2b
2b + b = 57, 3b = 57, b = 19.
s = 2b = 2(19) = 38.
sweater costs 38 dollars, and blouse costs 19 dollars
You can write it as:
-8 + 4 + -9
Subtracting a negative is the same thing as adding a positive. Hope this helps!
