Christine crawled:
3 ft* (3/4)= 2.25 ft.
3 ft+ 2.25 ft= 5.25 ft
We already know that 1 ft= 12 in.
5.25 ft* (12in/ 1 ft)= 63 in.
The total distance the two children crawled together is 63 in~

Answer:
Step-by-step explanation:
First you need to convert it to a linear expression. 
3x - y = 4
+3x        +3x
-1y = 3x + 4
---  ----- -----
-1     -1    -1
y = -3x -4
6x - 2y = 7
-6x         -6x
-2y = -6x + 7
----    -----   -----
-2       -2     -2
y = 3x - 3.5
-3x - 4 = 3x - 3.5
+3x         +3x
-4 = 6x - 3.5
+3.5       +3.5
-0.5 = 6x
-----   -----
6         6
-0.5
------ =  x
6
