Answer:
Here now the Coefficient of x is same that is 12.
[tex]12x+18y=36[/tex]
Step-by-step explanation:
Given:
[tex]12x+6y=13[/tex] ....Equation ( 1 )
[tex]4x+6y= 12[/tex] ....Equation ( 2 )
To Solve:
To make coefficients that are equal for x ?
Solution:
[tex]12x+6y=13[/tex] ....Equation ( 1 )
We will make Equation ( 2 ) coefficient same by multiplying throughout by 3 we get
[tex]3\times (4x+6y)=3\times 12[/tex]
Applying Distributive Property A(B+C)=AB+AC we get
[tex]3\times 4x+3\times 6y=3\times 12\\\\12x+18y=36[/tex]........as required
Here now the Coefficient of x is same that is 12.
