$- 2.1 y - 3 = - 1.8$ $-2.1 y -3 = -1.8$

adding $3$ $3$ to both sides we get;

$- 2.1 y - 3 + 3 = - 1.8 + 3$ $-2.1 y -3 +3 = -1.8 + 3$

$- 2.1 y = 1.2$ $-2.1 y = 1.2$

dividing both sides by $- 2.1$ $-2.1$

$\frac{- 2.1 y}{- 2.1} = \frac{1.2}{- 2.1}$ $(-2.1 y) /-2.1 = 1.2 / -2.1$

$y = - \frac{1.2}{2.1}$ $y = - 1.2 /2.1$

$y = - \frac{0.4}{0.7}$ $y = -0.4/ 0.7$

How do you solve −2.1y−3=−1.8-2.1y-3=-1.8?
