What is the solutions of 2x+y=5 and 3y=15-6x

Can someone answer these problems for me

Two positive integers are 3 units apart on a number line. their product is 108. which equation can be used to solve for m, the greater integer? m(m – 3) = 108 m(m + 3) = 108 (m + 3)(m – 3) = 108 (m – 12)(m – 9) = 108

When 142 is added to a number the result is 64 more times the number my options are 35 37 39 41
