The solution to given system of equations are 
<em><u>Solution:</u></em>
Given that we have to find solution to the system of equations
<em><u>Given equations are:</u></em>
x + 2y = 10 ------ eqn 1
y = 12x + 3 ------ eqn 2
We can solve the above equations by substitution method
<em><u>Substitute eqn 2 in eqn 1</u></em>
x + 2(12x + 3) = 10
x + 24x + 6 = 10
25x = 10 - 6
25x = 4

<em><u>Substitute the above value of x in eqn 2</u></em>

Thus the solution to given system of equations are 
The last one, since one depends on the other
It is 2i I standing for imaginary since it is a negative
square root of -1×4
4 square rooted is 2
and a negative number square rooted is i
Answer:
Okay the question is a little unclear, but if he's only doing english, science and history the answer should be <u> 17/40</u>
Step-by-step explanation:
1/5=8/40
3/8=15/40
8/40+15/40=23/40
40/40-23/40=17/40
Hello!
Let's multiply each thing here.
4(4)=16
3(5)=15
15=16=31
50-31=29
Therefore, her change is $29.
I hope this helps!
