Part a.
w=3.5t+8
w=3.25t+24

how do i solve these step by step? ?

t = 64 and W = 232

Step-by-step explanation:

W = 3.5t + 8

W = 3.25t + 24

If W equals an expression, and W equals another expression, the two expressions must be equal.

Since W = 3.5t + 8 and W = 3.25t + 24, using the substitution property of equality, you get

3.5t + 8  = 3.25t + 24

Subtract 3.25t from both sides.

0.25t + 8 = 24

Subtract 8 from both sides.

0.25t = 16

Divide both sides by 0.25.

t = 64

Now substitute 64 for t in the first original equation to find W.

W = 3.5t + 8

W = 3.5(64) + 8

W = 232

t = 64 and W = 232
