Answer:
x=771
Step-by-step explanation:
−771 + x = 0
x − 771 = 0
x − 771 + 771 = 0 + 771
Y+9=1/5x menjadi y= 1/5x -9
sesudah ini sibtusika n dalam persamaan 4x - 5y = -15x
<span> 4x -5(1/5x-9)= -15 x
4x + x+45=-15x
5x +45 = -15x 45=-20x
x=-45/20
x= -9/4
y+9 =1/5x
y = 1/5(-9/4)-9
y = -189/20
(-</span>9/4,-189/20)
