Answer:
41/30
Step-by-step explanation:
4/5 ---> 24/30
1/10 ---> 3/30
2/3 ---> 20/30
(24/30 - 3/30) + 20/30 =
21/30 + 20/30 =
41/30

Answer:
there's only one solution for the x value
Step-by-step explanation:
-253-1+352=10x+1
99=10x
99/10=x
9,9 = x
Answer:
y = 66
Step-by-step explanation:
11 = y/6
11*6 = y
66 = y
Answer:
x = 1/2 y = -5/2
Step-by-step explanation:
Since we already know an equation for y, we just need to plug it into the other equation.
21x - 7(-5x) = 28
21x + 35x = 28
56x = 28
x = 1/2
Now that we know x, we substitute it into the other equation, to find y.
y = -5x
y = -5(1/2)
= -5/2
