Question

Solve system of equations by cross multiplication method??
3x - y =40 and 4x - 2y = 50​

Answer 1

Answer:

x=15 y=5

Step-by-step explanation:

just solve the equations by multiplying 2 to 3x-y=40, which becomes 6x-2y=80 and subtract 4x-2y=50 from it

Then u get 2x=30 so x=15

Plug 15 into any of the x in the equation

Then u get y=5
