Question

find the solution of this system of equations. separate the x- and y-values with a comma x=-2+y -16x-3y=-25

Answer 1

X = -2 + y
-16x - 3y = -25

Let's substitute x into the second equation, since the first equation already tells us what x is.

Multiply -16 by x, which is (-2 + y)

-16(-2 + y) -3y = -25

Simplify.

32 -16y -3y = -25

Simplify. Get the variable on one side.

-19y = -57

Divide both sides by -19 to solve for the variable.

y = 3

Now plug y = 3 into one of the equations to find x. I'll use the first equation, since it's easier.

x = -2 + y
x = -2 + 3
x = 1

The answer is x= 1, y =3, which may be written as (1, 3). Hope this helps.
