Solve 4x + 11 = k for x.

steposvetlana [31]

Answer:

Step-by-step explanation:

Simplifying

4x + 11 = k

Reorder the terms:

11 + 4x = k

Solving

11 + 4x = k

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-11' to each side of the equation.

11 + -11 + 4x = -11 + k

Combine like terms: 11 + -11 = 0

0 + 4x = -11 + k

4x = -11 + k

Divide each side by '4'.

x = -2.75 + 0.25k

Simplifying

x = -2.75 + 0.25k

1) The sum of three numbers is 22. The second is 3 more than the first. The third is

Mila [183]

Answer: The numbers are 5, 8, and 9

Step-by-step explanation:

x+y+z=22

y=x+3

z=2x-1

After you have those three equations, you can plug the y and z value into the first equation.

You get x+x+3+2x-1=22, so 4x+2=22

Therefore, 4x=20, so x=5

If x=8, then y=5+3, so y=8

Also, z=2(5)-1, so z=9
