21 is the only solution of that equation.
True because in both equations x = 0 or x = -4
True
True
Yes, it is true.
Since 30=30 it is TRUE
True because in both equations x = 0 or x = -4
True.
True
true
True
Is |-8|+|3|=|-8+3| true or false?
Yes, it is true.
False
first we assume this to be true. x+1=x+2 x=x+1 x-x=1 0=1 this is not true, so the initial premise that this problem has a solution must be false. There is no solution.
Since 30=30 it is TRUE
false. because 5plus 3 plus 7 equals, 15, and 15 plus three is not seven
True
