Answer:
Step-by-step explanation:
Given the simultaneous equation
2x - y = 11. Equation 1
6x – 3y = 15. Equation 2
Using elimination method
Multiply the coefficient of x in equation 1 (which is 2) to equation 2. Also, multiply the coefficient of x in equation 2 (which 6) to equation 1. By doing this we are going to eliminate x
2x - y = 11. × 6 Equation 1
6x – 3y = 15. ×2 Equation 2
12x-6y=66. Equation 3
12x-6y=30. Equation 4
Subtract equation 4 from 3
Then (12x-6y) - (12x-6y) =66 -30
0=36
Which is not possible
Then the system has no solution, it has no solution at all. Because 0 is not equal to 36. If has been 0 equals to 0, then we may many solutions for simultaneous equation.

Answer:because it wants to know the answer cause maybe it’s a little elephant child
Step-by-step explanation:
Answer:
0.025 Kg/ cm²
Step-by-step explanation:
if two variables vary inversely, there is a negative relationship between both variables. the increase in one variable leads to a decrease in the other variable
the equation that represents inverse proportion :
where b = constant of proportionality
to determine the answer in this question :
1. determine constant of proportionality
200 = k / 32
k = 6400
2. Determine the amount of pressure using the constant of proportionality
256, 000 = 6400 / pressure
pressure = 6400 / 256, 000 = 0.025
