please help me!!!!!!!!!!!!!!!!
its about the triangle system. where we have to find the triple pair.
please help me...show work
2x+5y+2z= -5
-3x+3y+5z= 2
x+4y-z= 3
One way to start is to subtract the first equation from twice the third equation and add the second equation to three times the third equation, which will give you two simultaneous equations in y and z. Solve for y and z, then substitute back into one of the three given equations to find x.
