<span>30x + 20 = 50
</span>
<span>20 + -20 + 30x = 50 + -20

</span>0 + 30x = 50 + -20 30x = 50 + -20
<span>50 + -20 = 30 30x = 30
</span>
<span>x = 1</span>

30x - 20 = 50
use inverse operations to isolate x

30x - 20 = 50
+ 20 +20

30x = 70
(30x = 70) /30

x= 7/3 (this is the simplified term)

One of two complementary angles is 4 degrees more than the other. Find the angles. (Recall that complementary angles are angles

emmasim [6.3K]

$\displaystyle \\ 
\alpha + \beta = 90^o \\ 
\alpha - \beta = 4^o \\ 
\texttt{----------- } + \\ 
2\alpha ~~/~= 94^o \\ \\ 
\alpha = \frac{94}{2} = \boxed{47^o}\\ \\ 
 \beta = 90 -\alpha = 90 - 47 = \boxed{43^o}

When two variables are side by side do you multiply them?

Flauer [41]

Yes, if there's nothing separating the two variables (like "+" or "-") then you'd multiply them.

For example, ab means you multiply a times b.
