Answer:
5 + 2x = 6
2x = 6-5
2x = 1
x = 0.5
n -3n = 14 -4n
-2n = 14-4n (since 4n is negative, change the sign to make it positive and then add 4n to both sides of the equation)
2n = 14
n = 7
7 (5a - 4) - 1 = 14 - 8a
35a - 28 - 1 = 14 -8a
35a -29 = 14 - 8a
43a = 43
a = 1
Step-by-step explanation:
1.
5 + 2x = + 6
2x=6-5
2x=1
[tex]x \ = \frac{1}{2} [/tex]
2.
n - 3n = 14 - 4n
-2n= 14 -4n
-2n+4n=14
2n=14
n=7
3.
7(5a - 4 ) - 1 = 14 - 8a
35a-28-1=14-8a
35a-29=14-8a
35a+8a=14+29
43a=43
a= 1
