Tema [17]
From 1st equation
d + e = 2
d = 2 - e

From 2nd equation, subtitute d with 2 - e
d - e = 4
2 - e - e = 4
2 - 2e = 4
-2e = 2
e = -1

Find d
d = 2 - e
d = 2 - (-1)
d = 3

The solution is (3,-1)

Help me please????????
Evgesh-ka [11]

1) G=140º - angles on a straight line add to 180, H=140º - corresponding angles are congruent

2) set up the equation, since co-interior angles add to 180º the equation should be: x+40+3x+60

add like terms

4x+100=180

subtract 100

4x=80

divide by 4

x=20

3. the angles given are alternate angles meaning they are congruent, set up and equation: 3x-10=7x-42

add like terms

-4x=52

divide by 4

x=-13

To find angle DHG input the answer into the angles equation

7(13)-42

91-42

49

DHG=49º
