Question

V+8w=4v,for v

-m+5n=-2, for n

Answer 1

1. Value of v = (8w)/3
2. Value of n = (m - 2)/5

Explanation:

1) v + 8w = 4v, for v?

→ v + 8w = 4v

→ 8w = 4v - v

→ 8w = 3v

→ [ v = (8w)/3 ]

Thus, value is (8w)/3.

2) -m + 5n = -2, for n?

→ -m + 5n = -2

→ 5n = -2 + m

→ 5n = m - 2

→ [ n = (m - 2)/5 ]

Thus, value is (m - 2)/5.

Answer 2

• v = 8w/3,
• n = (m - 2)/5.

---------------------------

Given equations

• v + 8w = 4v and - m + 5n = - 2

Solve the first equation for v

• v + 8w = 4v
• 4v - v = 8w
• 3v = 8w
• v = 8w/3

Solve the second equation for n

• - m + 5n = - 2
• 5n = m - 2
• n = (m - 2)/5
