4+2.3y=1.7y-20

4 + 2.3 y = 1.7 y - 20

y = - 40

Solution steps

4 + 2.3 y = 1.7 y - 20

Multiply both sides by

10

40 + 23 y = 17 y - 200

Move

40

to the right side

23 y = 17 y - 240

Move

17 y

to the left side

6 y = - 240

Divide both sides by

6

y = - 40

x, x - \frac{y}{3} = 1

x, (\frac{x}{3}) + (\frac{y}{4}) = 1

\frac{4}{3} (\frac{2 + x}{5}) = \frac{1}{5} (8 - \frac{6 x}{3}) + \frac{5 x}{3}

6 x - 10 = 4 (x + 3)

\frac{t}{2.7} = \frac{4}{3.6}
