a. x=35
b. x=0.35
c. x=3.5
d. x=7
e. none of the above

Answer 1

add like terms , so you add the x's

Answer 2

(i'm going to feel really i dunno if i get this wrong) but after i did all of the work for each one, i got E. none of the above

Answer 3

i thought i was just supposed to plug the numbers into the x's and so like (for example A.)
0.1(35) + 0.03(35) + 0.35 =0.2(35)

Answer 4

you get .13x+.35=.2x
-.35 -.35
.13x=-.35+.2x
-.2x -.2x
-.07 x=-.35
_____________
-.07 -.07
x=5
