m = -12
3m + 7 = 5 Subtract 7 from both sides: 3m = -2 Divide both sides by 3: m = -2/3
17
4m + 3m = 180 7m = 180 m = 25 5/7
3m-5 = 7-21 3m = 7-21+5 3m = -9 m = -3
m = -12
If 3m - 7 = 8, then m = 5
3m + 11n = 3
3m + 7 = 5 Subtract 7 from both sides: 3m = -2 Divide both sides by 3: m = -2/3
17
-3m + 8 - 7 = -3m + 1
4m + 3m = 180 7m = 180 m = 25 5/7
3m-5 = 7-21 3m = 7-21+5 3m = -9 m = -3
-6 plus 2f plus 3f equals 29 -6 + 2f + 3f = 29 -6 + 5f = 29 5f = 35 f = 7
if x2 + 7 = 37, then x2 = 29 and x = ±√29
The equation 3m - 3m - 7 = 0, simplifies to -7 = 0 this means that the the solution is no solution, since -7 doesn't equal 0.
Placing a question mark at the end of a list of expressions or numbers does not make it a sensible question.
