#48 - v#

#21 - 8(v-3) + 3 + 7v#

First, combine like terms: #color(blue)((21 + 3))#
#24 - 8(v-3) + 7v#

To simplify this, use the distributive property:

Following this image, we know that:
#color(blue)(-8(v-3) = (-8 * v) + (-8 * -3) = -8v + 24)#

Therefore, the expression becomes:
#24 - 8v + 24 + 7v#

Combine like terms:
#48 - v#

Hope this helps!
