4k+44 = 10 k -10
-4k -4k
44 = 6k-10
+10 +10
54=6k
54/6 = 6k/6
9=k hope this helps
Ok so
t=number of text messsages
p=number of picture messages
total number is 33
t+p=33
if text is 0.18 per pic and picture is 0.45 per text
total cost is 8.3
0.18t+0.45p=8.3
times 100 both sides for ease
18t+45p=830
we now have 2 equations
t+p=33
18t+45p=830
multiply first equation by -18 and add to second equation
18t+45p=830
<span>-18t-18p=-594 +</span>
0t+27p=236
27p=236
divide both sides by 27
p=8.740740740740744
this is impossible becasue you can't send 0.740740740740744 of a message so you did a mistype somewhere

Answer: Because the y terms cancel
Step-by-step explanation:
Hi, this approach is called the addition method.
By adding both equations we can cancel one term that contains one variable, and calculate the remaining variable.
For example, in this case:
8x + 3y = 27
+
4x-3y = 9
_______
12x = 36
Now, we can solve for x:
x = 36/12
x = 3
Now, simple replace the value of x in any equation to obtain the value of y:
4x-3y = 9
4(3)-3y =9
12-3y =9
12-9 = 3y
3 =3y
3/3 =y
y=1
