Which linear equations have an infinite number of solutions? check all that apply. (x – 3\7) = 2\3 (3\2x – 9\14 ) 8(x + 2) = 5x – 14 12.3x – 18 = 3(–6 + 4.1x) 1\2(6x + 10) = 7(3\7x – 2) 4.2x – 3.5 = 2.1 (5x + 8)

Simplify each equation and look for ones which solve to a simple numeric equality:
First equation solves to -3/7=-18/42...take a 6 from 18 and 42, and you get -3/7. -3/7=-3/7 which is true - that means that, no matter what value is inserted for x, a true equation will result = infinite number of solutions
Second equation simplifies to 3x=-30. Nope
Third equation simplifies to -18=-18 = infinite number of solutions
Fourth eq: 5=-7/2 = No solution
5th eq: 6.2x=-3.5-16.2 = nope
