Question

6x +2y=4
y=-3x+2

Answer 1

i solved it by substituion method like this
6x+2y=4_y=-3x+2

Replace all occurrences of y with the solution found by solving the last equation for y. In this case, the value substituted is -3x+2.
6x+2(-3x+2)=4_y=-3x+2

Multiply 2 by each term inside the parentheses.
6x+(-6x+4)=4_y=-3x+2

Since 6x and -6x are like terms, add -6x to 6x to get 0.
0+4=4_y=-3x+2

Remove the 0 from the polynomial; adding or subtracting 0 does not change the value of the expression.
4=4_y=-3x+2

Since 4=4, the equation will always be true.
Always True_y=-3x+2

Answer 2

that is correct
another way of looking at it is that this means both equations represent the same line, thus every point on the line is a solution
Infinite solutions

Answer 3

solve the first equation for y get
\[y=-3x+2\] same as second equation. so you really have only one equation, they just look different

Answer 4

I have dependant, inconsistant, (1,-1) (2,0) for my answers

Answer 5

no there is not one answer or two answers. it is the same line
