Question

Помогите срочно!!!
1) |y|=9, 2) |x|=1,6. 3) |y|=5/9. 4) |x+7|=10. 5) |y-2|=5. 6) |y-1,7|=4

Answer 1

IyI=9
y₁=9    y₂=-9
IxI=1.6
x₁=1.6    x₂=-1.6
IyI=5/9
y₁=5/9    y₂=-5/9
Ix+7I=10
x₁+7=10    x₁=3
x₂+7=-10
x₂=-17
Iy-2I=5
y₁-2=5
y₁=7
y₂-2=-5
y₂=-3
Iy-1.7I=4
y₁-1.7=4
y₁=5.7
y₂-1.7=-4
y₂=-2.3
