Answer:
A. x = -7, B. x = -8, C. x = 9, D. x = 2, E. x = -3
Step-by-step explanation:
A. 4x= -28
Divide both sides by 4.
=
. x= -7
B. x- -6= -2 -> x+6= -2
Subtraction 6 to both sides.
x- +6-6= -2-6, x= -8
C. -x+= -9 -> x= 9
D. -3x+7=1
Subtraction 7 to both sides.
-3x+7-7 =1-7 , -3x=-6
Divide both sides by -3.
=
, x= 2
E. 25x+-11= -86 -> 25x-11= -86
Add 11 to both sides.
25x-11+11= -86+11, 25x= -75
Divide both sides by 25.
=
, x= -3
2. 2x+9= -15
Subtraction 9 to both sides.
2x+9-9= -15-9, 2x= -24
Divide both sides by 2.
=
, x= 12
I don't think there's an answer.
I hope it helps you!
Answer:
x = 2 degree and unknown angle = 31 degree
Step-by-step explanation:
149 + 13x + 5 =180 degree (being linear pair)
154 + 13x = 180
13x = 180 - 154
x = 26/13
x = 2 degree
unknown angle = 13x + 5
=13*2 + 5
=26 + 5
=31 degree
