<span>89+k=-42

We simplify the equation to the form, which is simple to understand
<span>89+k=-42

We move all terms containing k to the left and all other terms to the right.
<span>+1k=-42-89

We simplify left and right side of the equation.
<span>+1k=-131

We divide both sides of the equation by 1 to get k.
<span>k=-131.</span></span></span></span></span>

Answer:

$\sf\longmapsto \: x = 10$

Step-by-step explanation:

Subtract 7 from both sides:

7−5x−7=−43−7

Simplify:

−5x=−50

Divide both sides by −5:

$\sf\longmapsto \: \frac{ - 5x}{ - 5} = \frac{ - 50}{5}$

$\sf\longmapsto \: x = 10$

Answer:

m<M = 50°

Step-by-step explanation:

m<M +m<P +m<V=180° (sum of the interior angles of the triangle)

x+78+52°=180°

=>x+130= 180°

=>x=180°-130°

=>x= 50°
