The answer to the question “Round 0.423 to the nearest hundredth” is 0.42 because 3 is less than 5 and so 2 stays that way and so it is 0.42
Substitute y in 8x - 3y = -22.
8x - 3(5x + 19) = -22
Simplify.
8x - 15x - 57 = -22
Simplify.
-7x - 57 = -22
Add 57 to both sides.
-7x = 35
Divide both sides by -7.
x = -5
Substitute x in y = 5x + 19.
y = 5(-5) + 19
y = -25 + 19
y = -6
The solution is (-5, -6).
That would be 7 because 7x2=14 and 14-9=5
