M 2 = 2x°, m 3 = 5x°, m 1 = 2x + 5x 5x - 2x 180 - 5x 180 - 7x

MaRussiya [10]

We know: the sum of measures of triangle angles is 180°.

Therefore we have the equation

$m\angle1+m\angle2+m\angle3=180^o\to m\angle1=180^o-m\angle2-m\angle3$

Substitute $m\angle2=2x,\ m\angle3=5x$ :

$m\angle1=180-2x-5x=180-7x$

<h3>Answer: 180 - 7x</h3>

How do you answer this for a elimination simulatoneons equation

denis23 [38]

$\it 3x+2y=14
\\
5x-2y=18
\\
------\\
8x \ \ \ \ \ \ \ =32 \Rightarrow x = 32:8\Rightarrow x=4 \ \ \ (*)$

$\it 3x+2y=14 \stackrel{(*)}{\Longrightarrow} 3\cdot4+2y=14 \Rightarrow 12+2y=14 \Rightarrow 2y=14-12\Rightarrow 
\\\;\\
\Rightarrow 2y=2 \Rightarrow y=2:2 \Rightarrow y=1$

Therefore, the solution is: x = 4, y=1.
