There are two equations that we can use: 2x-y=0 and 4x+3y=0. Since none of them are solved for one variable, 2x-y=0 will be solved in terms of x. 2x-y=0 Add y to 0. 2x=y Substitute y=2x into 4x+3y=0. 4x+3(2x)=0 Distribute. 4x+6x=0 Combine like terms. 10x=0 Divide both sides by 10. $\frac{10y}{10}$=$\frac{0}{10}$ x=0 Substitute x=0 into x=2y to solve for y. y=2x y=2(0) y=0 The ordered pair would then be (0,0) since x=0 and y=0
