Which systems of equations have infinite solutions?

y=14-2x; 6x+3y=42

2x+y=17; -6x=3y-51

these are the answers :) brainliest?

answer: a

step-by-step explanation:

if xy ~ yz therefore xy would be the same length as yz

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
