The solution using correct step of substitution in the equation y=2x-1 4x+y=2 is x = 1/2 and y = 0
<h3>Simultaneous equation</h3>
y = 2x - 1
4x + y = 2
- Substitute the value of y in equation (1) into (2)
4x + y = 2
4x + (2x - 1) = 2
4x + 2x - 1 = 2
6x - 1 = 2
6x = 2 + 1
6x = 3
x = 3/6
x = 1/2
- substitute the value of x into equation (1)
y = 2x - 1
y = 2(1/2) - 1
= 2/2 - 1
= 1 - 1
y = 0

Answer:
Option B) is correct
The first four terms in the multiplication or geometric pattern has first term is 2 and then each term is multiplied by 7 is 2,14,98,686
Step-by-step explanation:
Given that the first term is 2 and then each term is multiplied by 7
When each term is multiplied by 7
That is formula used here is
put n=2 in
put n=3 in
put n=4 in
Therefore the pattern is 2, 14, 98, 686
Option B) is correct
