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

let h=-12, k=-11 then
(x-h)^2 + (y-k)^2= r^2
(x+12)^2 + (y+11)^2 = 7^2
x^2 + 24x + 144 + y^2 + 22y + 121 = 49
x^2 + y^2 + 24x + 22y + 144+121-49= 0
x^2 + y^2 + 24x + 22y + 216 = 0 is the required eq

Answer:
96
Step-by-step explanation:
y=8.3x
x=4
Substituting x as 4,
y=8*3*4
y=8*12
y=96
Hence, x=4, y=96
