7a + 10 = 2a 7a = 2a -10 5a = -10 a = -2
A=-4 b=5 2a=-8 2b=10 5ab=-100 2a x 2b x 5ab= -8000
Since the question is 3(2a), then just write it out. 3(2a) is 2a+2a+2a or 6a.
2A plus 3B times 2A - 3B = 4A2 - 9B2; this is an example of the general formula (a + b)(a - b) = a2 - b2.
52 times 2a = 104a
Algebraically, a times 2 is 2a.

a times 2 equals 2a
7a + 10 = 2a 7a = 2a -10 5a = -10 a = -2
No. 2a is one thing, 3b is another. If you add them together, they become 2a + 3b. 5ab indicates that multiplication has taken place. 5 times a times b = 5ab
2a*3 = 8+4a 6a = 8+4a 6a-4a = 8 2a = 8 a = 4
