Help me pls add in how to do it pls

Notice that the x coefficients are opposite in the two equations (in the first equation it's -1, in the seconds it's 1). So, if we sum the two equations, we will cancel out the x variable:

This equation works out to be

Now that we know the value for y, we can plug it into one of the two equations. The second one looks simpler, so we have

x=-3

y=-6

Step-by-step explanation:

the calculations are done above

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.
