Example

3(r+2s)=2t-4

a⋅(b-2)=3b

3(r+2s)=2t-4

a⋅(b-2)=3b

Question

$$2 b - 7 a + 8 a - 5 b + 3 c - c$$

Evaluate

$a-3b+2c$

Solution Steps

Combine $-7a$ and $8a$ to get $a$.

$$2b+a-5b+3c-c$$

Combine $2b$ and $-5b$ to get $-3b$.

$$-3b+a+3c-c$$

Combine $3c$ and $-c$ to get $2c$.

$$-3b+a+2c$$

Differentiate w.r.t. b

$-3$
