Answer: no solutions.

Step-by-step explanation:

get y by itself on one equation.

-4x + y = 3 ... add 4x to each side.

y = 4x + 3

plug in 4x + 3 for y in the other equation.

8x - 2y = 1

8x - 2(4x+ 3) = 1 ... plug in the y value

8x - 8x + 3 = 1 ... distribute the 2

3 = 1 ... solve

3 does not equal 1 so it is no solutions.

Answer:

We conclude that:

$c=-\frac{5n}{3\left(-n+2\right)};\quad \:n\ne \:2$

Step-by-step explanation:

Given the expression

$\frac{4}{2n}+\frac{5}{3c}=1$

<u>Let us solve for 'c'</u>

$\frac{4}{2n}+\frac{5}{3c}=1$

Least Common Multiplier of 2n, 3c: 6nc

Now multiply both sides by LCM = 6nc

$\frac{4}{2n}\cdot \:6nc+\frac{5}{3c}\cdot \:6nc=1\cdot \:6nc$

Simplify

$12c+10n=6nc$

Subtract 10n from both sides

$12c+10n-10n=6nc-10n$

Simplify

$12c=6nc-10n$

Subtract 6nc from both sides

$12c-6nc=6nc-10n-6nc$

Simplify

$12c-6nc=-10n$

Factor 12c - 6nc = 6c(2-n)

$6c\left(2-n\right)=-10n$

Divide both sides by 6(2-n); n≠2

$\frac{6c\left(2-n\right)}{6\left(2-n\right)}=\frac{-10n}{6\left(2-n\right)};\quad \:n\ne \:2$

simplify

$c=-\frac{5n}{3\left(-n+2\right)};\quad \:n\ne \:2$

Therefore, we conclude that:

$c=-\frac{5n}{3\left(-n+2\right)};\quad \:n\ne \:2$
