Answer:
x=1/2
Step-by-step explanation:
10-2x=14x+2
8/16=16x/16
x=1/2
Step-by-step explanation:
b+133=180
b=180-133
b=47
a+71+40=180
a+111=180
a=180-111
a=69
c+64=180
c=180-64
c=116
140=d+47
140-47=d
d=93
e+47+47=180
e+94=180
e=180-94
e=86
Answer is 44-2/5
Step by step. I did a print screen showing how we can use cancellation with the 3 and 9 so the numbers are smaller. Then we multiplied across to get 222/5.
