Question

Solve the system of equations. y = 4x + 6 3x + y = 41

Answer 1

→ Chapter : Linear Equation of Two Variables ←
≡ We know that:
↔ y = 4x + 6

⇔ 3x + y = 41
↔ y = 41 - 3x

≡ Solution:
⇔ First, find the value of x:
⇒ y = y
⇒ 4x + 6 = 41 - 3x
⇒ 4x + 3x = 41 - 6
⇒ 7x = 35
⇒ x = 5

⇔ Then, find the value of y:
⇒ y = 4x + 6
⇒ y = 4(5) + 6
⇒ y = 20 + 6
⇒ y = 26

∴ So, the solution of that equation is (5, 26)
