Question

Linear Equations by Substitution (w/ Sol'n.)
Please Kindly Solve :)

x + 4y =8
2x + 8y = 3

Answer 1

Since we are going about this using substitution, lets take that first equation and solve for x:
\[x+4y = 8 \Leftrightarrow x = 8-4y\]
Now we are going to substitute that value of x into the second equation:
\[2x+8y = 3 \Leftrightarrow 2(8-4y)+8y = 3 \Leftrightarrow 16-8y +8y = 3\]
but this leads to 16 = 3, which is a false statement. This shows that this system of equations has no solution.

Answer 2

if anything isnt clear, feel free to ask me to clarify. :)

Answer 3

if you look at the top equation and multiply thru by 2 you get
2x + 8y = 16 this is contridicting the other equation therefore unsolvable!

Answer 4
