Question

Which equation is equal to 4a+2b=10 A. b=-2a+10 B. 2a+5 C. b=-2a+5 D. b=2a+10

Answer 1

4a + 2b = 10

you are solving for b

isolate the b

subtract 4a from both sides

4a (-4a) + 2b = 10 (-4a)

2b = 10 - 4a

divide 2 from both sides to isolate the b

2b(/2) = (10 - 4a)/2

b = (10 - 4a)/2

b = 5 - 2a

C) b = -2a + 5 is your answer

hope this helps
