Answer:
x = 6
Step-by-step explanation:
Combine like terms here (anything with the same variable)
5x - 9x = -4x
6-2x = -4x+6
Add the lowest term in both sides
-2x + 4x = 2x
2x - 6 = 6
Add 6 to make 2x alone in order to get x
2x = 12
Divide both of the sides by 2 because that is how you get x all by itself
x = 6
Explanation:
A system of equations are two or more equations that has to be valid at the same time. It means that the variables of one equation can be substitute in the other equation.
For example we have <span>y=5x−8</span> and we can substitute this value of y in the other equation
<span>4x+3y=33</span>
<span>4x+3<span>(5x−8)</span>=33</span> we can solve now for x
<span>4x+15x−24=33</span>
<span>19x=33+24</span>
<span>19x=57</span>
<span>x=<span>5719</span>=3</span>.
y can be obtained from the first equation
<span>y=5x−8</span>
<span>y=5⋅3−8=15−8=7</span>
Then <span>x=3</span> and <span>y=7</span>.
Answer:
-10°
Step-by-step explanation:
take 24°+8°= 32
beacuse there was a decrease of 7° per hour for 6 hours you must subtract 7° six times from 32°
