X is 80
y is 100
z is 63
let me know if you dont understand how to get them, i will gladly explain how step by step
8(c-9) = 6(2c-12)-4c
Okay let us solve it together.
Multiply out and expand the brackets.
8*c -8*9 = 6*2c -6*12 -4c
8c -72 = 12c -72 -4c Re arrange by taking the cs to one side
8c -12c +4c = -72 + 72
0 = 0
For this kind of statement it means C can be any number, and it would satisfy the equation.
Cheers.

Answer:
T3 = 30
Step-by-step explanation:
9x + 3y - 6z = 18. 6. 3x-5y+10z= 15.
10x + 4y+5z = 20
6y-4=4y+2
2y=6, so y=3.
Plugging it in, you get that AC equals 4*3+2=14.
This is an isosceles triangle.
