Solve for the value of v.

Step-by-step explanation:

In the diagram, there are 2 angles: 105° and (8v+3)°. They are on a straight line together, so they are supplementary angles. They must add to 180 degrees. We can set up an equation.

We are solving for v, so we must isolate the variable. First, we can rearrange the right side and combine the like terms (the constants without a variable).

108 is being added to 8v. The inverse operation of addition is subtraction. Subtract 108 from both sides of the equation.

v is being multiplied by 8. The inverse operation of multiplication is division. Divide both sides by 8.

v is equal to 9.
