You asked:
Solve the system of equations −(7x)+y=−19, −(2x)+3y=−19 by elimination.
MathBot Answer:
xy=2=−5
−7x+y−2x+3y=−19=−19
Eliminate x from equation 2 by multiply both sides of equation 1 by −72, and adding the results to both sides of equation 2.
−7x+y719y=−19=−795
Solve equation 2 for y, and substitute the solution into the remaining equations.
−7xy=−14=−5
Solve equation 1 for the remaining unknown x.
xy=2=−5
