Solve the system algebraically. y = 3 -1/2 x 3x + 4y = 1 what is the value of x?

Step-by-step explanation:

You can use the Method of substitution.

Substitute the equation into the equation and then you must solve for the variable x:

Apply Distributive property:

Subtract 12 from both sides of the equation and then add the like terms. Then you get:

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
