Answer:
y = 6
x = 2
Step-by-step explanation:
rearrange the first equation in terms of x
x = (y - 2)/2
substiute x in the second equation
y = -5[(y-2)/2] +16
Now simpilify and solve for y
y = (-5y + 10)/2 +16
y = -5/2y + 5 + 16
y + 5/2y = 5 + 16
3.5y = 21
y = 6
Now substitue y in the first equation to solve for x
x = (6 - 2)/2
x = 2
Answer:
Step-by-step explanation:
It is 15 3/4 Because 2 negatives equal a positive
and that means u add ur whole numbers. The Denominator stays the same the top number gets added or multiplied
if its right Mark brainliest u dont have to
Answer:
Step-by-step explanation:
I'm just going to go out on a limb here and assume that those are a set of poorly made parenthesis. This, then, would be your equation:
![x+\frac{x}{7}+\frac{1}{11}(x+\frac{x}{7})=60](https://tex.z-dn.net/?f=x%2B%5Cfrac%7Bx%7D%7B7%7D%2B%5Cfrac%7B1%7D%7B11%7D%28x%2B%5Cfrac%7Bx%7D%7B7%7D%29%3D60)
The first thing to do is distribute through the parenthesis to get:
![x+\frac{x}{7}+\frac{x}{11}+\frac{x}{77}=60](https://tex.z-dn.net/?f=x%2B%5Cfrac%7Bx%7D%7B7%7D%2B%5Cfrac%7Bx%7D%7B11%7D%2B%5Cfrac%7Bx%7D%7B77%7D%3D60)
Next is to get rid of the denominators by multiplying by the LCM of 77:
which gives you:
77x + 11x + 7x + x = 4620 and
96x = 4620 so
![x=\frac{385}{8}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B385%7D%7B8%7D)
X = 12
y = 9
z = 11
good luck :))
Answer: +3
