180 is 6x larger than 30, and 30 is 6x larger than 5. so y is 6x larger than x, and n is 30
You can see almost immediately that the second equation, 3x + y = -2, can be solved for y: y = -3x - 2. (Answer A). This -3x - 2 can in turn be subbed for y in the first equation, 4x + 3y = 4. Doing so, we get 4x + 3(-3x - 2) = 4.
Carrying out the indicated opeations: 4x - 9x - 6 = 4, or -5x = 10. Thus,
x = -2. Find y using y = -3x - 2 (from above): y = -3(-2) - 2 = 4.
Thus, the solution is (-2,4). We were not asked to solve this system of equations, but doing so illustrates the helpfulness of elimination of variables in solving simultaneous equations.
This means that your coefficient of correlation indicates strong correlation between the Independent variable and the dependent variable
