Answer:
x = 17
Step-by-step explanation:
Combine like terms first:
x + 3x + 4 = 72 --> 4x + 4 = 72
Isolate the variable by subtracting 4 from both sides so you get
4x = 72 - 4
4x = 68
Divide both sides by 4 to get
x = 68/4
x = 17
354 / 4 = 88.5
so2 numbers below that and 2 numbers above that:
87 + 88 + 89 +90 =
2nd number is 88

Answer:
consistent, independent
Step-by-step explanation:
Systems of equations are most easily classified these ways if the equations are in the same form. If we solve the second equation for y, we have ...
y = x - 1
The x-coefficients of this and the first equation are different, so the system is <em>consistent</em> and <em>independent</em>.
__
A system is independent if the equations describe different lines.
A system is inconsistent if the equations describe parallel lines.
Here, the different lines are not parallel, so the system is independent and consistent.
