2x + 3x + x + 60= 180
6x + 60= 180
6x° = 120°
x° = 20°
(2x)°= 40°
(3x)°= 60°
(x+60)°= 80°

Answer:
Infinite solutions
Step-by-step explanation:
In this question, you have to solve the systems of equations.
This means that we have to find the value of x and y.
Solve:
Let solve for x in one of the equations first:
6x - 8y = 10
Add 8y to both sides.
6x = 8y + 10
Divide both sides by 6.
x = 8/6y + 10/6
Simplify.
x = 4/3y + 5/3
Now, plug in the new equation to "x" in our second equation:
3(4/3y + 5/3) -4y = 5
Solve:
3(4/3y + 5/3) - 4y = 5
Distribute the 3, which cancels the denominators.
4y + 5 - 4y = 5
Combine like terms.
5 = 5
Since they equal the same thing, there are infinite solutions.
