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

On Monday, there is 1 option.
On Tuesday, there are 2 options.
On Wednesday, there are 5 options.
On Thursday, there are 4 options.
On Friday, there is 1 option.
The number of combinations is 1 × 2 × 5 × 4 × 1 = 40.
This is the commutative property, because the order in which you multiply does not change the product.
