Answer:
-41
Step-by-step explanation:
if you plug -2 everywhere you see an x and 1 everywhere you see a y, and then simplify you get -41
We can just substitute y = 4x+1 in the second equation.

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

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.
