7a + 4 = 5a + 7 7a = 5a + 3 2a = 3 a = 3/2

It's a simple algebraic equation.If the value of 'a' is needed, it can be derived as follows:7a + 10 = 2aSubtract 2a from each side:5a + 10 = 0Subtract 10 from each side:5a = -10Divide each side by 5:a = -2

Add them together: 2a+5a = 7a

2a

7a-17 = 4a+1 7a-4a = 1+17 3a = 18 a = 6

7a + 10 = 2a 7a = 2a -10 5a = -10 a = -2

-7a+2a+9 is also -5a+9. -5a+9=24. -5a=15. a=-3.

2a + 10 + 5a - 2 = (2a + 5a) + (10 - 2) = 7a + 8

7a + 4 = 5a + 7 7a = 5a + 3 2a = 3 a = 3/2

2a+5a=3 7a=3 a=3/7 or .4286

eleven! doo doo doo doot

a/5 + a/2 = 14/2 2a/10 + 5a/10 = 7 7a/10 = 7 7a = 70 a = 10

It is: 2a+5a = 7a when simplified

Collect like terms: 9a -7a = 9 - 15, ie 2a = -6, so a = -3

Add them together: 2a+5a = 7a
