2x-7=5+x =>
2x-x=5+7 =>
x=12
So, yes 12 is the only solution to this equation.
21 is the only solution of that equation.
0 = 12 is neither. It is a false statement.
True because in both equations x = 0 or x = -4
False. 54 cm equals 540 mm.
false
21 is the only solution of that equation.
0 = 12 is neither. It is a false statement.
False, think of each linear equation as the graph of the line. Then the unique solution (one solution) would be the intersection of the two lines.
false, there is a solution -34x - 9 = 24 +9 +9 -34x = 33 x= - 33/34 or x = -.970588
True because in both equations x = 0 or x = -4
False.
False.
false
The answer is "FALSE".
4a + 6 - 4a = -10 Combining like terms: 6 = -10 or 4 = 0 which is FALSE. So the solution set is empty.
true false
False. 54 cm equals 540 mm.
