4((2-7y)/(21))+y=1

4 (\frac{2 - 7 y}{21}) + y = 1

y = - \frac{13}{7}

Decimal Notation

y = - 1.85714 \dots

Solution steps

4 (\frac{2 - 7 y}{21}) + y = 1

Expand

4 (\frac{2 - 7 y}{21}) + y : \frac{8}{21} - \frac{y}{3}

\frac{8}{21} - \frac{y}{3} = 1

Multiply both sides by

3

\frac{8}{7} - y = 3

Move

\frac{8}{7}

to the right side

- y = \frac{13}{7}

Divide both sides by

- 1

y = - \frac{13}{7}

X, A X = B

- 5 (- x + 3) + 3 = - x + 8

3 (4 - 7 x) + 3 x = - 8 (3 + 3 x)

6 - x = 3 - 4 x

x, x + 3 y - 2 = 0
