Question

A) |2x - 4| + |x + 3| = 14

b) x^2 + 6x = 7

Answer 1

A) |2x - 4| + |x + 3| = 14
2x - 4 + x + 3 = 14
3x = 15

b) x^2 + 6x = 7
x^ 2 + 6x = 7
x^ + 6x = 5
6x do sześcianu = 5

Czy to o to chodzi ??

Answer 2

(2x - 4) + (x + 3) = 14
3x-1=14 |+1
3x=15 |/3
x=5

Answer 3

2x+x=14+4-3
3x=15
a jak masz wyznaczyć x to jeszcze 3x+15/:3
x=5

no a b to 2x+6x=7
8x=7
