Answer:

Step-by-step explanation:

11x + 23 = 8x + 35

3x + 23 = 35

3x = 12

x = 4

11(4) + 23 = 44 + 23 = 67 for m<CBD

8(4)+35 = 32 + 35 = 67 for m<ABD

Find the solution of this system of equations.
solmaris [256]
X=5+y

Substitute the value of x in second equation
28x – 9y= -12
28 (5+y)-9y =-12
140 +28y -9y =-12
140 +19y= -12
19y = - 152
y= -8



Now let's find the value of x using y

x= 5+y
x= 5 + (-8)
= -3

So,
x= -3
y=-8
