Answer» Answer: Enter a problem... Algebra Examples Popular PROBLEMS Algebra Solve for x 3x-7=0 3 x − 7 = 0 Add 7 to both sides of the equation. 3 x = 7 Divide each term by 3 and simplify. Tap for fewer steps... Divide each term in 3 x = 7 by 3 . 3 x 3 = 7 3 3 . Tap for fewer steps... Cancel the common factor. 3 x 3 = 7 3 Divide x by 1 . x = 7 3 The RESULT can be shown in multiple forms. Exact Form: x = 7 3 Decimal Form: x = 2. ¯ 3 Mixed Number Form: x = 2 1 3 |
