Answer:
No solution
Step-by-step explanation:
3x + 5 - x = 2(x-1)-4
2x + 5 = 2x - 2 - 4 Add the like terms. Distribute the 2.
2x = 2x - 6 - 5 Subtract 5, add like terms
2x = 2x - 11 Add like terms
0 ≠ -11 Subtract 2x to keep variables on one side
Since zero does not equal -11, there are no solutions
Number the tables as follows:
1 2
3 4
Eliminate 3 and 4 immediately, because for x = 2 the y values are wrong (3 and 1).
In tables 1 and 2, the input (1) produces the correct output (-1).
So we have to determine which table agrees 100% with the system of equations given.
Comparing tables 1 and 2, row by row, we see that their contents are the same EXCEPT for the first rows. So focus on determing which of those 2 rows displays values that satisfy both given equations.
First I looked at y=2x-5, and subst. -1 for x. I got -7, which is correct in table 1 but not in table 2 (where the value would be -13).
Thus, table 1 correct represents the solution of the system of equations.
