Thread: Elimination method help

Can someone please show me how to do number 49?

for each equation, start with by distributing and collecting like terms to get each equation in the form ax + by = c ... it will then be fairly obvious what to multiply one of the equations by to eliminate one of the variables (it will be y in this case). you should end up getting positive integer solutions for x and y.
