Solve the following equations a. X + 8 = 15

b. 4x = -28

c. 3x - 4 = 11

d. 7y - 2 3/4 = 1/2

Please also give an explanation.

a. X = 7

b. X = -7

c. X=5

d. Y= 13/28

Step-by-step explanation:

a.

group like terms

b.

Divide both sides by 4

c.

group like terms

Divide both side by 3

d.

LCM =4

hope it

step-by-step explanation:

x^(1/6) · x^(1/6) · x^(1/6)   ·x^(1/6) = x^(4/6)   since we add the exponents

4/6 can be simplified to 2/3

the simplified form is x^(2/3)
