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

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

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

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

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

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

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

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

(7a=3)=(-a-5)=16

2a - 4y = 3a - 8a - 5y 7a = -ya = -(y/7)

5a³ - 4ab + 2a³ = (5+2)a³ - 4ab = 7a³ - 4ab.

5a + 3 = 7a - 1 add 1 to both sides 5a + 4 = 7a so 4 = 2a as 5a + 2a = 7a 4 = 2a = 2 x 2 so a = 2 Check: then 5a + 3 = 10 + 3 = 13 and 7a - 1 = 14 - 1 = 13

It is: -7a when simplified

9a-a = 19+7a 8a = 19+7a 8a - 7a = 19 + 7a - 7a 1a = 19 a = 19
