Which linear equations have an infinite number of solutions? Check all that apply. (x – ) = (x – left-parenthesis x minus StartFraction 3 Over 7 EndFraction right-parenthesis equals StartFraction 2 Over 3 EndFraction left-parenthesis StartFraction 3 Over 2 x EndFraction minus StartFraction 9 Over 14 EndFraction right-parenthesis.) 8(x + 2) = 5x – 14 12.3x – 18 = 3(–6 + 4.1x) (6x + 10) = 7(StartFraction one-half EndFraction left parenthesis 6 x plus 10 right-parenthesis equals 7 left-parenthesis StartFraction 3 Over 7 x minus 2 right-parenthesis. x – 2) 4.2x – 3.5 = 2.1 (5x + 8)
