Question

I would love some help on this

Answer 1

• A. ⅔ x + 6 = 16
• D. 12
• C. 2
• A. -36

Explanation:

Solution -1

A ) ⅔ x + 6 = 16

→ ⅔ × 15 + 6 = 16

→ 10 + 6 = 16

→ 16 = 16

Proved

• LHS = RHS

B ) ⅓ x + 4 = 22

→ ⅓ × 15 + 4 = 22

→ 20 = 2

Not Proved

C) 3x + 15 = 30

→ 3×15+15 = 30

→ 3× 30 =30

→ 90= 30

Not Proved

D) x + 25 = 50

→ 15 + 25 = 50

→ 40 = 50

Not Proved

• option a is correct answer

Solution -2

10r -24 = 7r + 12

→ 10r - 7r = 12+24

→ 3r = 36

→ r = 12

• Option d is correct answer

Solution. -3

3r -2r-8 = -8r + 10

→ 3r - 2r + 8r = 10+8

→ r + 8r = 18

→ 9r = 18

→ r = 2

• Option c is correct answer

Solution - 4

m/3-18 = m + 6

→ 54- m/ 3 = m + 6

→ 54- m = m + 6×3

→ 54- m = m + 18

• Here one side m is positive and one side m is negative so both will cancel .

→ 18 - 54

→ -36
