Solving linear equations
AlexFokin [52]

Answer:

(x, y ) = ( \frac{1}{2}, \frac{5}{2})

Step-by-step explanation:

given the 2 equations

4x + 2y = 7 → (1)

y = 5x → (2)

Substitute y = 5x into equation (1)

4x + 2(5x) = 7

4x + 10x = 7

14x = 7 ( divide both sides by 14 )

x = \frac{7}{14} = \frac{1}{2}

substitute this value into equation (2)

y = 5 × \frac{1}{2} = \frac{5}{2}
