Solve and express the solution set in simplest form.

4x−1/3=7/1

{4/3}

{3/2}

{7/3}

{11/2}

Step-by-step explanation:

The equation to be solve is

4x−1/3=7/1

We can go about this by first adding 1/3 to both sides.

We then simplify the the right hand side of the equation

To find x, we multiply through by 1/4

Hence the solution set in the simplest form for the expression is

{x=11/2}

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
