2a + 10 + 5a - 2 = (2a + 5a) + (10 - 2) = 7a + 8
5a + 3 + (2a - 2) + a= 5a + 3 + 2a - 2 + a= 8a + 1
6a + 4 = 5a - 2 means that 6a - 5a = -2 - 4 which gives a = -6
5a + 2 = 7 subtract 2 from both sides: 5a = 5 divide both sides by 5: a = 1
-5a + b = 2 AND -a - 5b = 0 -5a + b = 2 b = 2 + 5a *using above -a - 5b = 0 -a - 5(2 + 5a) = 0 -a - 10 - 25a = 0 -26a = 10 a = 10/-26 *using 'a' value 5a + b = 2 5(10/-26) + b = 2 -25/13 -2 = -b b = 51/13 Therefore a = 10/-26 b = 51/13
(5a)^2 or a^2+10a+25
4a^2 - 5a^2 = -a^2
It is the 5 in 5a+2
5a(a+2) = 5a^2 + 10a
2a + 10 + 5a - 2 = (2a + 5a) + (10 - 2) = 7a + 8
5a + 3 + (2a - 2) + a= 5a + 3 + 2a - 2 + a= 8a + 1
In mathematics, the term "5a squared" can be written as "5a^2". This expression represents the product of 5 and the square of the variable "a". To calculate the value of 5a^2, you would square the value of "a" and then multiply the result by 5.
6a + 4 = 5a - 2 means that 6a - 5a = -2 - 4 which gives a = -6

5a or 4a squared
5a = -5a + 5Add 5a to each side:10a = 5Divide each side by 10:a = 5/10 = 1/2
5a^2 - 5a - 60 ---- 5(a2 + a - 12)
