The restrictions for the equation is that the denominator can not be zero. So the restrictions for x would be what values make the denominator zero.
7x^2 + 6x = 0
factor
x(7x + 6) = 0
multiply any number by 0 and you get 0. So either x = 0 or 7x+6 = 0
since there's a x in the numerator x/x = 1 so this will not be a restriction. Then the only restriction is:
7x+6 = 0
7x = -6
x = -6/7
Answer:
Step-by-step explanation:
13.
6 =x − 24
Collecting like terms
6 + 24 = x
x = 30
14.
10 +w/3 = 2
Multiply each term by 3
30 + w = 6
Collecting like terms
w = 6 - 30
w = -24
15.
13 = −11 − 4x
Collecting like terms
4x = -11 - 13
4x = -24
Dividing by 4
4x/4 = -24/4
x = -6
