Answer:
x, y = (0, 0)
Step-by-step explanation:
photo math broo
x=2, y=1
4x+8y=16
4x-8y=0
Add the two equations together:
8x=16
Divide both sides by 8:
x=2
Plug this back into one of the original equations to find y:
4(2)-8y=0
8-8y=0
y=1
Hope this helps!
19.10
If im correct,
You subtract 10 and 5. Wich is 5. Then multiply that by 3.82.
a:) Integer Sequences
b:) 1, 3, 6, 10, 15, 21, 28, 36, 45, 55, 66, 78, 91, 105, 120, 136, 153, 171, 190, 210, ...
z + 12 = 9
Reorder the terms:
12 + z = 9
Solving
Solving for variable 'z'.
Move all terms containing z to the left, all other terms to the right.
Add '-12' to each side of the equation.
12 + -12 + z = 9 + -12
Combine like terms: 12 + -12 = 0
0 + z = 9 + -12
z = 9 + -12
Combine like terms: 9 + -12 = -3
z = -3
Simplifying
x = - 6
- 15/3 = x + 1
- x = 1 + 15/3
- x = 3/3 + 15/3
- x = 18/3
x = - 18/3
6966
7740*10%=774
7740-774=6966
