Question

5(x-3y)-2x=6 and x=3y
Solve the equations please by substitution

Answer 1

Answer for the first equation:

(7, -1)

Explanation:

Original Equation: 5(x - 3y) - 2x = 6 When x = 3y

Substitute in the 3y for x:

5(3y - 3y) - 2(3y) = 6

5(0) - 6y = 6

-6y = 6

y = -1

Plug -1 in for y in the original equation:

5(x -3(-1)) - 2x = 6

5(x + 3) - 2x = 6

5x + 15 - 2x = 6

3x + 15 = 6

3x = -9

x = -3

Answer 2

x= -3 , y=-1
hope this helped !!
