Answer:
x =8
The angles are
3x= 24
7x+4 = 60
13x-8 =96
Step-by-step explanation:
The sum of the angles of the triangle is 180
3x+ 7x+4 + 13x-8 =180
Combine like terms
23x -4 = 180
Add 4 to each side
23x -4+4 =180+4
23x =184
Divide by 23
23x/23 = 184/23
x =8
The angles are
3x= 3*8 =24
7x+4 = 7*8+4 = 56+4 = 60
13x-8 = 13*8-8 =104-8=96

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)
