Answer:
Below.
Step-by-step explanation:
As both the right sides of the 2 equations are equal to y, by the transitive law of equality 3x + 1 = -2x + 3.
W then solve this equation for x then substitute this value of x in the first equation ( y = 3x + 1) to find the value of y.
The answer is -1 because, -2x+-6 = -4 is the same as -2x=2 which equals -1
When you have minus negative it is the same result as plus positive, so 3+4 is what you're looking for
