Use substitution to solve the system of equations x= -3y-13 2x+2y=-6

For this case we have a system of two equations with two unknowns:

To solve we follow the steps below:

We substitute the first equation in the second:

We apply distributive property to the terms of parentheses:

We add 26 to both sides of the equation:

We find the value of x:

what is the image?

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
