Answer:
5 * .487 = 2.435
Step-by-step explanation:
5 * 487 = 2435
There are 3 digits after the decimal in the original problem, so there will be 3 digits after the decimal in the answer
5 * .487 = 2.435
2x + y - z = -3 .....multiply by 2
5x - 2y + 2z = 24
-----------------
4x + 2y - 2z = -6 (result of multiplying by 2)
5x - 2y + 2z = 24
----------------add
9x = 18
x = 18/9
x = 2
3x - z = 5
3(2) - z = 5
6 - z = 5
6 - 5 = z
1 = z
2x + y - z = -3
2(2) + y - 1 = -3
4 + y - 1 = -3
y + 3 = -3
y = -3 - 3
y = -6
solution is : (2.-6,1)

Answer:
wait 2022?!?!?!!?
Step-by-step explanation:
The 2 is in the x place.
Let's substitute 2 for x in our equation.
2(2)-5y=11
Now, we can solve for y. (the other coordinate)
4-5y=11
Subtract 4 from each side.
-5y=7
Divide by -5.
y = -7/5 or -1 2/5 or -1.4
