Use properties to rewrite the given equation. which equations have the same solution as x + + x = – x plus startfraction 2 over 3 endfraction plus x equals startfraction one-half endfraction minus startfraction 1 over 5 endfraction x. x? select three options. x + startfraction 8 over 5 endfraction x plus startfraction 2 over 3 endfraction equals startfraction one-half endfraction minus startfraction 1 over 5 endfraction x. = – x plus startfraction 2 over 3 endfraction plus x equals startfraction one-half endfraction minus startfraction 1 over 5 endfraction x. x 18x + 20 + 30x = 15 – 6x 18x + 20 + x = 15 – 6x 24x + 30x = –5 12x + 30x = –5
