Question

find the value of x from the pair of linear equations x+3y=6 and 2x-3y=12​

Answer 1

Step-by-step explanation:

There are three methods from which you can complete this question and find the value of X.

1. substitution method

2. elimination method

3. cross multiplication method

We'll perform Substitution Method

= X+3y=6

= X=6-3y

Substituting values of X in equation 2.

= 2x-3y=12

= 2(6-3y)-3y=12

= 12-6y-3y=12

= 12-9y=12

= -9y=12-12

= -9y=0

= y=0

X=6-3y

X=6-3(0)

X=6-0

X=6
