Question

Solve 7 + x - 15 = -2.



5

6

10

20

Answer 1

\[7 + x - 15 = -2\]\[7 + x - 15 +15= -2+15\]\[7 + x = 13\]\[7 + x -7= 13-7\]\[x=~?~~you~~tell~~me.\]

Answer 2

idk thats why i asked

Answer 3

I did all the steps. You just have to do the last hit.

Answer 4

\(x=6\)

Answer 5

Yeah, how great we are at giving the answers....

not even thinking about anything.....

Answer 6

Solve for y.

7y - 6y - 10 = 13



y = -23

y = -3

y = 3

y = 23

Answer 7

7y-6y-10=13
y-10=13
y=23

Answer 8

Which of the following equations has the solution set {0}?



-14m - 7m + 1 = -7m + 1

-14m + 7m + 1 = -7m + 2

14m - 7m - 1 = -7m + 1

Answer 9

\( 7y-6y-10=13\)
\(\Leftrightarrow y=13+10\)
\(\Leftrightarrow y=23\)

Answer 10

The equation has the solution set {0} is \(-14m - 7m + 1 = -7m +1\)
Because: If \(m=0\), them \( -14\times 0 - 7\times 0 + 1 = -7\times 0 + 1\) \(\Rightarrow 1=1\) (always satisfy)
