Answer:
Step-by-step explanation:
When solving equations with fractional or decimal coefficients, the equations needs to be multiplied by the multiple of denominator such that the equations have integer coefficients and constants
Answer:
(-2,3)
Step-by-step explanation:
I used Desmos to input these 2 equations and then locate the point(s) at which they intersect. Since these are both linear, there will be either 1 solution or none at all, but in this case, there is one solution, and it is at the point (-2,3) which is where the 2 graphs intersect.

3 tests at 75% each = 3 x 75 = 225 total points
First two tests = 79 + 84 = 163
Third test needs to be at least: 225 - 163 = 62%
So any score less than 62 would get you into trouble.
