3(x-7)=x+11
3x-21=x+11
3x=x+11+21
3x=x+32
3x-x=32
2x=32
x=32/2
x=16
Answer:
s + 3w = 64
Step-by-step explanation:
s represents the amount of strawberry juice
w represents the amount of water
then,
s + 3w = 64
To find x:
ON is parallel to LM
8x - 8 = 7x + 4
-7x -7x
1x - 8 = 4
+8 +8
1x = 12
--- ---
1 1
x = 12
8(12) - 8 = 7(12) + 4
96 - 8 = 84 + 4
88 = 88
------------------------------------
To find y:
NM is parallel to OL
x - 5 = 3y - 6
12 - 5 = 3y - 6
7 = 3y - 6
+6 +6
13 = 3y
--- ---
3 3
13/3 = y
Check:
12 - 5 = 3(13/3) - 6
7 = 13 - 6
7 = 7
