Solve for a. 6 ( a 3 ) = 18 6a a. no solution b. all real numbers c. −3 d. −1

6(a + 3) = 18 + 6a
6a + 18 = 18 + 6a
6a - 6a = 18 - 18
0 = 0

The solution is all real numbers.

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
