Answer 1

A) 5x-31=227
5x=227+31
5x=258
x= 258/5= 51.6
B)6w-13-w=42-2w
6w-w+2w=42+13
9w=54
w=54/9
w=6
D)7Y+60-2Y=91-Y+23
7Y-2Y+Y= 91+23-60
6Y= 54
Y=54/6
Y=9
F) 9W-217=30
9W=30+217
9W= 247
W= 247/9
W= 27.44
G) 12Y+61=37-2+64
12Y= 37-2+64-61
12Y= 38
Y= 38/12
Y=3.17
H) 62+7Y= 2Y+119-3
7Y-2Y = 119-3-62
5Y=54
Y= 54/5
Y= 10.8
I)6w-512=49+31
6w= 49+31+512
6w=592
w=592/6= 98.67
J)7N-13-46=13
7N= 13+13+46
7N= 72
7N= 72/7= 10.285
K)8x-x+19=3x+300
8x-x-3x= 300-18
4x= 282
x=282/4=70.5
L)63+12=69+7x
63+12-69=7x
6=7x
x=0.857
M)34x-23+x=69+7x
34x+x-7x=69-23
28x=46
x=46/28= 1.642
N) (2x+37)(6)-4=50
12x+222-4=50
12x=50+4-222
12x= -168
x= -168/12=-14
O)9(x+3)=126
9x+27=126
9x=99
x=99/9=11
