solve the folling equation using grammars 2x+4y+z=9
To solve the equation 2x + 4y + z = 9 using grammars, we need to rearrange the equation in terms of one of the variables and then substitute the values of the remaining variables.
Step 1: Rearrange the equation
The goal is to isolate one variable on one side of the equation. Let's rearrange the equation by moving all the terms that don't contain 'x' to the other side:
2x = 9 - 4y - z
Step 2: Substitute the values of the remaining variables
Now that 'x' is isolated, we can substitute known values for 'y' and 'z' to find the value of 'x'.
For example, if we know that y = 2 and z = 3, we can substitute those values into the equation:
2x = 9 - 4(2) - 3
Simplifying this expression, we have:
2x = 9 - 8 - 3
Step 3: Solve for 'x'
Now, we can solve for 'x' by performing the arithmetic operations:
2x = -2
To isolate 'x', we can divide both sides of the equation by 2:
x = -2/2
x = -1
Therefore, when 'y' is equal to 2 and 'z' is equal to 3, the value of 'x' in the equation 2x + 4y + z = 9 is -1.
