Question 157972: 30=14-2x

You can put this solution on YOUR website! 30=14-2x (move x to left of equation sign)
30+2x=14+2x-2x
30+2x=14
30-30+2x=14-30 (move numbers to right of equal sign and combine like terms)
2x=-16 (solve for x by dividing)
2x/2=-16/2
x= -8
check by substituting -8 for x
30= 14 -2-(8)
30=14 +16
30=30
