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 =![\frac{y+r}{m}](/tpl/images/1065/3668/fb55a.png)
(3)
2x + 3y = 10 ( subtract 2x from both sides )
3y = 10 - 2x ( divide both sides by 3 )
y =![\frac{10-2x}{3}](/tpl/images/1065/3668/10949.png)
(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 =![\frac{5x-4}{3}](/tpl/images/1065/3668/5a926.png)
