Answer:
x = 19
Step-by-step explanation:
When two lines "cross" and intersect, it creates 2 pair of vertical angles.
The opposite angles are vertical angles and they are equal.
Given two angles (in expressions), they are vertical angles and hence are equal in measure. So we can write:
Now, we can use algebra and solve for x:
So,
x = 19

Answer:
Infinite many solutions. Any x-value can satisfy the equation.
Step-by-step explanation:
Let's work on simplifying the equation a little to investigate which x-values satisfy it. Start by combining like terms on the left side (6x +4x=10x),
then distribute the factor "10" into the binomial (x+10), obtaining 10x +30.
Now we have the same expression on the left and the right of the equal sign:
10x +30=10x+30. We may subtract 30 from both sides, and obtain 10x=10x, and at this point divide by 10 both sides, and we obtain: x=x
The process is shown below.
x=x is an equation that is verified by absolutely ANY x value on the number line, and there are infinite x-values in the number line.
Therefore there are infinite many solutions to this equation (any x-value will satisfy it).
