Question

X+y+z+11=v
solve for z

Answer 1

Explanation:

x+y+x+11=y

Combine x and x to get 2x.

2x+y+11=y

Subtract y from both sides.

2x+11=y−y

Combine y and −y to get 0.

2x+11=0

Subtract 11 from both sides. Anything subtracted from zero gives its negation.

2x=−11

Divide both sides by 2.

x= -11/2

Answer 2

z=v-x-y-11
