implifying

4z + -15 = 4z + 11

Reorder the terms:

-15 + 4z = 4z + 11

Reorder the terms:

-15 + 4z = 11 + 4z

Add '-4z' to each side of the equation.

-15 + 4z + -4z = 11 + 4z + -4z

Combine like terms: 4z + -4z = 0

-15 + 0 = 11 + 4z + -4z

-15 = 11 + 4z + -4z

Combine like terms: 4z + -4z = 0

-15 = 11 + 0

-15 = 11

Solving

-15 = 11

Use the diagram below to find the measured value of x.
dexar [7]

Answer:

They're the same angle. I would look up transversals so you could understand it a bit more. I'll upload a picture of a transversal in my answer but you should search it anyways.

Anyways,

To solve, you set 160 equal to the other side.

160 = 3x + 10

150 = 3x

x = 50
