Solve the following system of equations by using the substitution method. x – y = 3 2x + 2y = 2 (3, 4) (-4, 5) (2, -1)

Solution :

Given equations,

Applying Substitution method to solve the equation.

Solve the first equation for x,

Substitute the value of x in second equation,

To calculate the value of  x  substitute the value of y in first equation

Hence, the solution of the equations is (2,-1).

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!
