Question

Is (–6, –9) a solution to this system of equations?
13x − 8y = –6
y = –9

Answer 1

Take one of the equations and solve for one of the variables. For example, take

3x-4y=2 --> 3x = 4y+2 --> x = (4y+2)/3

Answer 2

@jhonyy9 ? ^ is that on the right track?

Answer 3

@karlieeeeeee

Answer 4

just substitute these value of x and y inside this equation make th calcule and look what will get

Answer 5

Oh so we will multiply -6 x 13 =?

Answer 6

all i did was replace -6 with x

Answer 7

13x -8y = -6

13*(-6) -8*(-9) = -6 so this is right ?

Answer 8

-78 +72 = ?

Answer 9

=-6

so -6 = -6

what result from these ?
