Set measurements equal to each other.
7X + 20 = 8X + 8
-7X -7X
20 = X + 8
-8 -8
ANSWER: X=12
Answer:
12
Step-by-step explanation:
The computation of the size of the customers is shown below:
Here we find the greatest common divisor of the given numbers
96, 60, 84 ÷ 2
48, 30, 42 ÷ 2
24, 15, 21 ÷ 2
12, 15, 21 ÷ 2
6, 15, 21 ÷ 2
3, 15, 21 ÷ 3
1, 5, 7 ÷ 5
1, 1, 7 ÷ 7
1, 1, 1
By this there are three numbers i.e. 2, 2 and 3
So, the lease common denominator is
= 2 × 2 × 3
= 12

Answer:
Equivalent systems of equations review
Step-by-step explanation:
We're given two systems of equations and asked if they're equivalent.
x + 4y = 8 (1)
4x + y = 2 (2)
Interestingly, if we sum the equations in System A, we get:
Replacing the first equation in System A with this new equation, we get a system that's equivalent to System A:
This is System B, which means that System A is equivalent to System B.
