Question

1 f (x)=x+7
2. f (x) = 7x-2
3 f (x) = 13x+ 2x-6
4 f(x) = x+3-5
5 f (x) = 4X-12

me ayudan con esto?​

Answer 1

1) f (x) = x + 7

0 = x + 7

x = - 7

2) f (x) = 7x - 2

0 = 7x - 2

x = $\frac{2}{7}$

3) f (x) = 13x + 2x - 6

0 = 13x + 2x - 6

x = $\frac{2}{5}$

4) f (x) = x + 3 - 5

0 = x + 3 - 5

x = 2

5) f (x) = 4x - 12

0 = 4x - 12

x = 3
