Respuesta :
2 times x(the unknown number to solve for) minus 1 equals 8+7
2x-1=8+7 8+7=15
2x+1=15 Now we have to get x by itself
In order to do that you add 1 from both sides
2x=16 Then you divide 2 from both sides
x=16/2
x=8
2x-1=8+7 8+7=15
2x+1=15 Now we have to get x by itself
In order to do that you add 1 from both sides
2x=16 Then you divide 2 from both sides
x=16/2
x=8
I think its probley 16 i dont really understand this question but im sure it is
