Multiply each member of this equation by (-2) and post the result here. Equation: 2x – 7y = 3

Top one by -2 :) -4x + 14y = -6 4x + 5y = -2 19y = -8 and you can work it from there :)

@ryan.g.campbell.17 ---> This question was for the Asker and not for your deus ex machina. Read the Code of Conduct. @raebaby420 Yes. The objective in the Addition/Subtraction method of solving simultanteous linear equations is to multiply by a number that will cause the coefficient of the variable you wish to eliminate to add out.
