Which of the following values of z will result in a true statement when substituted into the given equation?
2 answers:
Z=1 because if we plug it in we get 1/5(3+2(1))-4(1)=-3 and then that goes to 1/5(5)-4 = -3 then 1-4=-3 and that is true
Answer:
A) z=1
Step-by-step explanation:
1/5(3+2z)-4z=-3
3/5+2/5z-4z=-3
2/5z-20/5z=-3-3/5
-18/5z=-15/5-3/5
-18/5z=-18/5
z=(-18/5)/(-18/5)
z=1
