Question

What is the solution to the equation 2k-10/-7=8

Answer 1

`(2k-10)/(-7)=8 \\ - (2)/(7)k- (10)/(7)=8 \\ - (2)/(7)k-1.43=8 \\ +1.43\ \ \ \ \ \ +1.43 \\ - (2)/(7)k=9.43 \\ * -(7)/(2)\ \ \ \ * -(7)/(2) \\ \boxed{k=-33.005}`

Answer 2

`\sf(2k-10)/(-7)=8`

Multiply -7 to both sides:


`\sf2k-10=-56`

Add 10 to both sides:


`\sf2k=-46`

Divide 2 to both sides:


`\sf~k=-23`
