Question

61. Solve the equation 2a = 3a + 4c for a
A. a = -4c

B. a = 3 + 4c

C. a = 4c – 5

Answer 1

Start by subtracting 3a from both sides.

Answer 2

how?

Answer 3

2a=3a+4c
-3a -3a
-a = 4c

Does that make sense?

Answer 4

sort of

Answer 5

2a-3a=-a and (3a-3a)+4c = (0)+4c or just 4c

Answer 6

so now you have
-a=4c
so you want to multiply each side by -1 ro change the sign of a.

Answer 7

-4c
