Answer 1

Answer:

1.quesion..Substitute the equation (x = 7) into a two-variable equation.Can be written as

Step-by-step explanation:

1.answer..In general, it is obvious that if we want to write an equation ax=0 in terms of two variables then it may be written as ax+(0×y)=0.

Hence, the equation x=7 can be written in two variables x and y as:

(1×x)+(0×y)=7

4..quesion.. If (2. 0) is a solution of the linear equation 2x 3y = k. So what is the value of & # # 6 2 5 4x

answer.. If (2,0 )is a solution of a linear equation then the value of x=2 and value of y=0 if we put the value of x and y in the equation then

2x+3y=k

⇒k=2×2+3×0

⇒k=4

Hence the value of k=4
