Question

How many solutions can be found for the equation 4z + 2(z - 4) = 3z + 11

Answer 1

one

Explanation:

i just took the test

Answer 2

4z+2(z-4)=3z+11 perform indicated multiplication on left side

4z+2z-8=3z+11 combine like terms on left side

6z/-8=3z+11 add 8 to both sides

6z=3z+19 subtract 3z from both sides

3z=19 divide both sides by 3

z=19/3

z=6 1/3

So there is only one solution when z=6 1/3
