7-(3.1-0.1y)=3-0.2y

7 - (3.1 - 0.1 y) = 3 - 0.2 y

y = - 3

Solution steps

7 - (3.1 - 0.1 y) = 3 - 0.2 y

Expand

7 - (3.1 - 0.1 y) : 0.1 y + 3.9

0.1 y + 3.9 = 3 - 0.2 y

Move

3.9

to the right side

0.1 y = - 0.2 y - 0.9

Move

0.2 y

to the left side

0.3 y = - 0.9

Divide both sides by

0.3

y = - 3

9 x^{2} - 16 y^{2}

- 5 - 4 x = 3 - 2 x - x^{2}

ln (e^{10})

\frac{x}{5} = 2

2 ∣ x + 3 ∣ - 4 > 6
