Answer:
x=64/31
Step-by-step explanation:
31x-4+120=180
31x+116=180
subtract 116 from both sides
Simplify
Divide both sides of the equation by the same term
get answer x=64/31
Answer:
The Biden administration is extending a mask mandate for airplanes and transit for 15 days, the Centers for Disease Control and Prevention said Wednesday.
The mandate was set to expire after April 18, following a one-month extension announced in March. Airlines have required masks on planes since early in the pandemic in 2020, but the Biden administration made them mandatory in early 2021.
The CDC said it is monitoring the spread of omicron, including the BA.2 subvariant.

Answer:
x= -54
Step-by-step explanation:
-4x - 84 = 2x + 24
-4x + 2x= 24 + 84
-2x= 108
x= 108 ÷ (-2)
x= -54
I think 12 percent but sorry if I got it super wrong
3x + y = 3
7x + 2y = 1
First isolate one of the variables (x or y) in one of the equations.
Isolate "y" in the first equation(because it is the easiest to isolate) and substitute it into the second equation.
3x + y = 3 Subtract 3x on both sides
3x - 3x + y = 3 - 3x
y = 3 - 3x
7x + 2y = 1
7x + 2(3 - 3x) = 1 [since y = 3 - 3x, you can substitute (3-3x) for "y"]
Multiply/distribute 2 into (3 - 3x)
7x + (3(2) - 3x(2)) = 1
7x + 6 - 6x = 1
x + 6 = 1 Subtract 6 on both sides
x = -5
Now that you know "x", substitute it into one of the equations (I will do both)
3x + y = 3
3(-5) + y = 3 [since x = -5, you can plug in -5 for "x"]
-15 + y = 3 Add 15 on both sides
y = 18
7x + 2y = 1
7(-5) + 2y = 1
-35 + 2y = 1 Add 35 on both sides
2y = 36 Divide 2 on both sides
y = 18
x = -5, y = 18 or (-5, 18)
