How can you get coefficients that are equal for x?
12x + 6y= 13
4x+6y= 12

Here now the Coefficient of x is same that is 12.

Step-by-step explanation:

Given:

....Equation ( 1 )

....Equation ( 2 )

To Solve:

To make coefficients that are equal for x ?

Solution:

....Equation ( 1 )

We will make Equation ( 2 ) coefficient same by multiplying throughout by 3 we get

Applying Distributive Property A(B+C)=AB+AC we get

........as required

Here now the Coefficient of x is same that is 12.

lk

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get
