subtract 2a so u have 7x = 3a - 2a + 5a. Simply that and you have 7x = 6a. divide by 7 and you have...
x = 6/7 a
2007-11-24 06:03:31 · answer #1 · answered by Zach S 4 · 1⤊ 1⤋
7x + 2a - 2a = 3a + 5a - 2a
7x + 0 = 8a - 2a
7x = 6a
7x / 7 = 6a / 7
x = 6a / 7
For check
7( 6a / 7 ) + 2a = 3a + 5a
6a + 2a = 8a
8a = 8a
therefor the answer is correct

7x = 3a +5a -2a
7x = 6a
x = 6/7 a

7x+2a=3a+5a
7x+2a-2a=8a-2a
7x=6a
7x divided by 7=6a divided by 6
x=6a over 7

7x+2a=3a+5a
7x+2a=8a
7x=6a
x=6a/7

rewrite by putting all like terms together...
7x = 6a
x = 6/7a
