Step-by-step explanation:

Given:-

a) 1/4 y +9 = 6

b)3( 2x -1) =1

To find:-

Solve the following equations

Solution:-

a)

Given equation is 1/4 y +9 = 6

=> 1/4 y = 6-9

=> 1/4 y = -3

=> y = -3×4

=> y = -12

The value of y = -12

Check:-

LHS:-

1/4 y+9

Put y = -12 then

=> 1/4 (-12)+9

=> (-12/4)+9

=>>(-3)+9

=> 6

=> RHS

LHS = RHS is true for y = -12

b)

Given equation is 3(2x-1 ) = 1

=> 6x -3 = 1

=> 6x = 1+3

=> 6x = 4

=> x = 4/6

=> x = 2/3

The value of x = 2/3

Check:-

LHS:-

3(2x-1)

Put x = 2/3 then

=> 3[2(2/3)-1]

=>3[(4/3)-1]

=> 3[(4-3)/3]

=> 3[1/3]

=> 3/3

=> 1

=> RHS

LHS= RHS is true for x = 2/3

Answer:-

a) The solution of 1/4 y +9 = 6 is -12

b) The solution of 3( 2x -1) =1 is 2/3
