Answer:
value of x = 5
Step-by-step explanation:
Given:
∠L = ∠n
So,
ML = MN
So,
3x = x + 10
2x = 10
x = 5
value of x = 5
I think the answer is 32 if I did my math right sorry if it wrong

Substitute the given value of y into the equation y=7x+15

Move the variable to the left-hand side and change its sign

Collect like terms

Divide both sides of the equation by -5

Substitute the given value of x into the equation y=2x

Solve the equation for y

The possible solution of the system is the ordered pair (x,y)
