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

Question

simsharrison · Answer

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

jhonyy9 · Answer

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

simsharrison · Answer

Oh so we will multiply -6 x 13 =?

simsharrison · Answer

all i did was replace -6 with x

jhonyy9 · Answer

13x -8y = -6

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