move the decimal point 2 places to the left
42.6 / 
= 0.426
I'll solve it algebraically
x+y=4
x-3y=12
multiply first equatoin by -1 and add to second
-x-y=-4
<u>x-3y=12 +</u>
0x-4y=8
-4y=8
divide both sides by -4
y=-2
sub back
x+y=4
x+-2=4
add 2 to both sides
x=6
x=6
y=-2
(6,-2)
They might stutter when they say words.
afterward they will start saying words like mom,cup,juice,food.
it just takes a while for their tongue to get used to saying words
