Answer:
Alright well solve first the variable in one of the equations, then substitute the result into the other equation
Point form: (1, 19)
equation form: x = 1 and y = 19
Hope this helps have a nice day :)
Step-by-step explanation:
Answer: The required value of y is 19.
Step-by-step explanation: We are given to find the value of y in the solution to the following system of equations :
[tex]y=12x+7~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)\\\\y=-6x+25~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(ii)[/tex]
Comparing equations (i) and (ii), we get
[tex]12x+7=-6x+25\\\\\Rightarrow 12x+6x=25-7\\\\\Rightarrow 18x=18\\\\\Rightarrow x=\dfrac{18}{18}\\\\\Rightarrow x=1.[/tex]
From equation (i), we get
[tex]y=12\times1+7=12+7=19.[/tex]
Thus, the required value of y is 19.
