Answer:
-2
Step-by-step explanation:
- 5x + 8 = 18
Take + 8 to the right hand side, it turns negative i.e -8
-5x = 18 - 8
-5x = 10
Divide both sides by the coefficient of x which is -5
-5x/5 = 10/-5
x = -2
D. 7
e. 4
f. 5
g. 11
Get these by adding/subtracting the number at the end (use the opposite operation) and then divide the coefficient from both sides.
1 = 32
2 = 148
3 = 32
4 = 148
5 = 32
6 = 148
7 = 32
8 = 148
Answer:
x= 6.6
LM= 33
MN= 17.2
LN=50
Step-by-step explanation:
10x-16= 5x+2x+4 (LN=LM+MN)
10x-16=7x+4
3x-16=4
3x=20
x=6.6
then plug 6.6 back into equation and round to the nearest whole number.
