Answer:
21+3x
Step-by-step explanation:
multiply the 3 by everything inside the parentheses
Could you maybe provide us with a better explantion or picture?
The anwser to your question is 1 and 5/7
For the first system, we have
1 - 3x + 3y = -8
or
-3x + 3y = -9
The second equation, however, tells us
-3x + 3y = 13
but -9 ≠ 13, so this system has no solution.
For the second system, notice that multiplying both sides of
4x - 8y = 6
by 1/2 gives
2x - 4y = 3
which is identical to the other equation in the system. Then all point (x, y) that lie on this line are solutions to the system, meaning there are infinitely many solutions.
