PLEASE HELP!!!! Solve the system of equation. Write the solution as a coordinate point.

Dovator [93]

We can just substitute y = 4x+1 in the second equation.

$6x-2(4x+1)=-3\\6x-8x-2=-3\\6x-8x-2+3=0\\-2x+1=0\\-2x=-1\\x=\frac{1}{2}$

We know the value of x, substitute x in any equations to get the y-value.

$4x+1=y\\4(\frac{1}{2})+1=y\\2+1=y\\3=y$

The value of y is 3 and the value of x is 0.5 aka 1/2

Since you want the solution as a point then It's below here.
