Question

SOLVE ONE STEP EQUATIONS-

show one step work-


`image`


then


`a+1 (1)/(6)= (3)/(4)`

Answer 1

The first question -

`- (2)/(9) = a + (7)/(6)`

`- (2)/(9) - (7)/(6) = a`

`a = - (4)/(18) - (21)/(18)`

`a = - (25)/(18)`

`a = - 1 (7)/(18)`

The second question -

`a + (7)/(6) = (3)/(4)`

`a = (3)/(4) - (7)/(6)`

`a = (9)/(12) - (14)/(12)`

`a = - (5)/(12)`

Hope that helps :)

Answer 2

`- (2)/(9) = a + (7)/(6)`

Take 7/6 to the other side


`- (2)/(9) - (7)/(6) = a`

Make both fractions have the same denominator


`a = - (2 * 2)/(9 * 2) - (7 * 3)/(6 * 3)`

Simplify


`a = - (25)/(18)`


The second question.


`a + (7)/(6) = (3)/(4)`

Bring 7/6 to the other side


`a = (3)/(4) - (7)/(6)`

Make both fractions have similar denominators.


`a = (3 * 3)/(4 * 4) - (7 * 2)/(6 * 2)`

Simplify


`a = - (5)/(12)`
