Answer:
x = 25
Step-by-step explanation:
4x+50 and 150 are vertical angles which means they are equal.
4x+50 =150
Subtract 50 from each side
4x+50-50 = 150-50
4x = 100
Divide each side by 4
4x/4 = 100/4
x = 25

Answer:
one solution : (2 ; 3)
Step-by-step explanation:
hello :
4x + 5y =23
...(*)
9x- 5y= 3....(**)
add (*) and (**) : 13x =26
x =26/13 = 2
put this value in (*) : 4(2)+5y = 23
5y =15
y =15/5=3
one solution : (2 ; 3)
