Given the numerical expression:
-7+x=x/10-16
Determine the answer.
Solution:
In order to determine the answer we must simplify the given numerical expression, by combining similar terms.
-7+x=x/10-16
Start by moving -16 on the other side of the equation, note that when moving a number, the sign changes.
-7+x + 16=x/10
9 + x = x/10
Multiply both sides by 10 in order to cancel out x/10
(10) 9 + x = x/10 (10)
x = 90 + 10x
transpose 10 x on the other side of the equation.
x - 10x = 90
-9x = 90
Divide both sides by -9 in order to get the value of x.
-9x/-9 = 90/-9
x = -10
Final answer: x = -10
