Answer:
This is a simultaneous equation
Step-by-step explanation:[tex]1-y=8x2-y=x+17Multiply equation 2 with -8 so that you can cancel out both 8y=8x-8y=-8x-1361y-8y=-7y+8x and -8x will cancel outso the equation is-7y=-136y=-136\frac{x}{y} -7y=19.428put the value of y in equation 119.428=8x19.428\frac{x}{y} 8=xso x=2.4285good luck[/tex]
