solvefor y,4.2x-1.4y=2.1

solve for

y, 4.2 x - 1.4 y = 2.1

y = - \frac{3 ( - 2 x + 1 )}{2}

Solution steps

4.2 x - 1.4 y = 2.1

Multiply both sides by

10

42 x - 14 y = 21

Move

42 x

to the right side

- 14 y = 21 - 42 x

Divide both sides by

- 14

y = - \frac{3 ( - 2 x + 1 )}{2}

\frac{1}{4} = \frac{x + 1}{4}

y, 8 x + 4 y = 12

y, 5 x - y = 0

y, 5 x - y = 1

\frac{- 2 - 7 x}{4} + 1 = \frac{1 - x}{5}
