Put both of those equations into slope intercept form (in order to be typed into the graphing calculator).
2x + 3y = 16.9
3y = -2x + 16.9
y = (-2/3)x + 16.9/3
5x = y + 7.4
5x - 7.4 = y
So in the graphing calculator,
Y1 = (-2/3)x + 16.9/3
Y2 = 5x - 7.4
Then find the point of intersection and the x value of that would be the solution.
You get the coordinate (2.3, 4.1). So x = 2.3, y = 4.1
▪ Answer:
x = 5/6
▪ Step-by-step explanation:
Hi there !
5/x = 25/6
x = 5×6/25
x = 30/25
simplist 5
x = 6/5
Good luck !
Look I only searched the answer but here it is.
