15t-20=6t-(t+2)+(-t+3)

15 t - 20 = 6 t - (t + 2) + (- t + 3)

t = \frac{21}{11}

Decimal Notation

t = 1.90909 \dots

Solution steps

15 t - 20 = 6 t - (t + 2) + (- t + 3)

Remove parentheses:

(- a) = - a

15 t - 20 = 6 t - (t + 2) - t + 3

Group like terms

15 t - 20 = 6 t - t - (t + 2) + 3

Add similar elements:

6 t - t = 5 t

15 t - 20 = 5 t - (t + 2) + 3

Expand

5 t - (t + 2) + 3 : 4 t + 1

15 t - 20 = 4 t + 1

Move

20

to the right side

15 t = 4 t + 21

Move

4 t

to the left side

11 t = 21

Divide both sides by

11

t = \frac{21}{11}

x, 6 x + 2 y = 10

x, x + y = - 6

x, x + 5 y = 5

4 x - (2 x - 1) + x = 2 x - (13 - x) - x

\frac{x - 4}{5} = \frac{x - 2}{3} - \frac{( x - 3 )}{4}
