What is the value of x?

x = 20

Step-by-step explanation:

Since the 2 angles are directly across from each other they share the same agle meaning u can make them equal to each other 3x+50=6x-10

So the rule of solving this type of equation is to get the variable on one side of the equation but u have to follow the zero property 3x-3x+50=6x-3x-10

So then u get 50 = 3x-10 so use the same rule to get the 10 to the other side 50+10= 3x-10+10

Then you get 60 = 3x then just use the division property of equality

60/3=3x/3 and x = 20

69

step-by-step explanation:

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.
