PLEASE HELP ASAP 25 PTS + BRAINLIEST TO RIGHT/BEST ANSWER

Answer:

(-2,-5)

Step-by-step explanation:

y = 2x-1

3x-y = -1

We can use substitution

3x - (2x-1) = -1

Distribute the minus sign

3x -2x+1 = -1

x +1 =-1

Subtract 1 from each side

x+1-1 = -1-1

x=-2

Now we need to find y

y = 2x-1

y = 2(-2) -1

y = -4-1

y = -5

(-2,-5)

$\large{\rightarrow{6\:(x\:+\:4)\:=\:-\:2\:(4x\:-\:4)\:+\:8x}}$

$\large{\rightarrow{6x\:+\:24\:=\:-\:8x\:+\:8\:+\:8x}}$

$\large{\rightarrow{6x\:+\:24\:=\:{\cancel{-\:8x}}\:+\:8\:+{\cancel{\:8x}}}}$

$\large{\rightarrow{6x\:+\:24\:=\:8}}$

$\large{\rightarrow{6x\:=\:8\:-\:24}}$

$\large{\rightarrow{6x\:=\:16}}$

$\large{\rightarrow{x\:=\:\frac{-\:16}{6}}}\\$
