Question

what is the solution to the system of equations of linear equations 2x + 4y = 38 and 10x + 3y = 105
what is the greatest common monomial factor of the expression 12x^2 y^3 - 48x^5y ?

Answer 1

A) 2x + 4y = 38
B) 10x + 3y = 105
Multiplying A) by -5
A) -10x -20y = -190 then adding it to B)
B) 10x + 3y = 105

-17y = -85
y = 5
x = 9
