Answer:
x=2
y=−1
Step-by-step explanation:
You can multiply the second equation by 3:
{2x-3y=7
{9x+3y=15 add the two together (in columns):
11x+0=22
so that x=22/11=2
substitute this back into the first equation:
2*2-3y=7
y=-1
2 = -x - 8 equation
x = -10
There are linear relationships so long as the power of x is 1 when power of y is 1 / power of x is not 2 and above when power of y is 1. This is assuming you plot the vertical axis as y-axis and the horizontal axis as the x-axis.
So using this concept, the equation with linear relationships are:
1, 3, 4, and 5.
