Solve these equations for brainliest need the answers asap :(
1. 21 = x/18
2. −9 + x = −26
3. 29 + n = 13
4. k + 1 = −27
5. 6 = m − 16
6. 5 = v + 29
7. 41k = −2747
8. −71 = x/64

ASAP
ALSO AN EXPLANATION OR JUST HOW TO DO THESE EQUATIONS

1. X= 378
2. X= -17
3. N= -16
4. K= -28
5. M= 22
6. V= -24
7. K= -67
8. X= -4544

And if the equation is dividing you divide both sides instead of multiplying both sides

The earth's inner core is the earth's innermost part. it is primarily a solid ball with a radius of about 1,220 km (760 miles), which is about 70% of the moon's radius.[1][2] it is composed of an iron–nickel alloy and some light elements. the temperature at the inner core's surface is approximately 5,700 k (5,430 °c), which is about the temperature at the surface of the sun.
