Answer:
the first number is 3.4 and the second number is 1
Step-by-step explanation:
The computation of the two numbers is shown below:
Let us assume the first number be x
And, the second number be y
Now the equations are
5x + 4y = 21
And,
5x + 9y = 16
Now subtract equation 2 from equation 1
-5y = -5
y = 1
And, the x is
5x + 4 = 21
5x = 17
x = 3.4
Hence, the first number is 3.4 and the second number is 1
Answer: y = 7
explanation: 6y = 6y + 7
y =
You are correct with both
Answer:
See below
Step-by-step explanation:
1) x=2-1
x=1
2) (x+1)(x+1)=2(x+1)
3) 10x-20 -11 = 4+3x
10x-3x=20+11+4
7x=35
x=5
