Answer:
x=3/4
Step-by-step explanation:
Set up an equation:
1/6+x=1 2/3-x
1/6+x=5/3-x
1/6+x=10/6-x
2x=9/6
2x=3/2
4x=3
x=3/4
Check:
common denominator of 12
2/12+9/12=11/12 AND 20/12-9/12=11/12

False
I think that’s right because three times 5 is 15 increased by four is 19 not -8 so...
<span>18z-7(-3+2z)
= 18z + 21 - 14z
= 4z + 21
answer is False
</span><span>coefficient of z is 4, not 13</span>
