Solve the literal equation for x

see explanation

Step-by-step explanation:

(1)

y = 5x - 7x , that is

y = - 2x ( divide both sides by - 2 )

x = - y

(2)

mx - r = y ( add r to both sides )

mx = y + r ( divide both sides by m )

x =

(3)

2x + 3y = 10 ( subtract 2x from both sides )

3y = 10 - 2x ( divide both sides by 3 )

y =

(4)

5x - 3y = 4 ( subtract 5x from both sides )

- 3y = 4 - 5x ( divide both sides by - 3 )

y = ( multiply numerator/ denominator by - 1 , to 'tidy up' )

y =
