You have not added your options, so I will just solve and hope that my answer is in your choices.
For the first equation we have:
3x-1=7+2
3x = 7+2+2
3x = 10
x = 10/2
For the second equation we have:
<span>2x+1+4=3
</span>2x = 3-4-1
2x = -2
x = -1
Therefore, there isn't a solution that satisfies both equations. Based on this, this system of equations has no solution.

Step-by-step explanation:
Alexis needs to score at least 96 points on her next test in order to have an average of at least 90.
explanation:
85+89+92+96= 360
359/4=90
Answer:
y-intercept: (0, 5); slope: 1/4
Step-by-step explanation:
The slope (m) is found from ...
m = (y2 -y1)/(x2 -x1)
Using the first two points in the table, this is ...
m = (8 -6)/(12 -4) = 2/8 = 1/4 . . . . . eliminates choices A and C
__
Then, the point-slope form of the equation of the line can be written as ...
y -y1 = m(x -x1)
y -6 = (1/4)(x -4) . . . fill in known values
y = 1/4x -1 +6 . . . . . add 6
y = 1/4x +5
Then the value of y when x=0 is ...
y = 0 +5 = 5
So, the y-intercept is (0, 5) and the slope is 1/4, matching the last choice.
