مساء الخير،
ممكن اتساعدوني في حل هالأسايمنت حق مادة ECON موعارفه أشلون أجاوب عليه وما أدري شنو علاقته بالمادة
1.3X + 2Y = 18
2X + 3Y = 12
Rewrite the equations to find the valus of X & Y
Draw the lines for the equations by calculating the coordinates of the lines
Sketch the lines of the following equations
Y=3X-2 when -1>= X >=3
Y=2X+3when -2<= X <=3
Y=X when -3<= X <=3
Write down the equations for the lines from the following ordered pairs of point
(1.-3) to (4,-5)
(2,3) to (-7,-8)
(2,4) to (3,9)
