Please help with these math problems thank you

Answer 1

A.

x/7 + x/7 =4

Calculate the sum

2/7x=4

multiply both sides of the equation by 7/2

x=14

b. 2x/3 - x/3 =4

Multiply both sides of the equation by 3

2x-x=12

collect like terms

x=12

c. 4x/5 - 2x/5 =7

Multiply both sides of the equation by 5

4x-2x=35

Collect like terms

2x=35

Divide both sides of the equation by 2

x= 35/2

d. x/6 + x/4 =3

Multiply both sides of the equation by 12

2x+3x=36

Collect like terms

5x=36

Divide both sides by five

x = 36/5

e. -x/-5 + x/4 =2

Multiply both sides by 20

-4x+5x=40

Collect like terms

x=40

f. x/3 - x/6 = 5

Multiply both sides by six

2x-x=30

Collect like terms

x=30

hope this helps!!
