-11=x-5
-11+5=x
-6=x
Long method:
-11=x-5
-11+5=x-5+5 ----> You do this to cancel the -5
-6=x ----> same as the one above
Assuming that the question is find x in x5=1610; the answer is 4.378901
x5 = x3 times x2. In this case x3 = 64 so x = cube root of 64 ie 4
5x-9Substitute 4 in for x5(4)-9=Solve.9-9=0the answer is zero.The answer is not zero you added when you were supposed to multiply so the real answer is 11.
x5 is an expression, not an equation nor an inequality. An expression cannot be solved.
1,565 = x5 1,5651/5 = (x5)1/5 1,5651/5 = x5/5 1,5651/5 = x 4.3541 = x
