Answer:

#-3x + 58#

Explanation:

First, we use the distributive property to multiply/expand #-8(-7+x)#:
#-8 * -7 = 56#
#-8 * x = -8x#

Now let's put that back into the expression:
#2 + 56 - 8x + 5x#

Now we can simplify by combining like terms:
#58 - 3x#

We usually write expressions with the variable first, so I'm going to rewrite it that way:
#-3x + 58#

Hope this helps!
