please tell me this​

Answer 1

Answer:

(a)-d

(b)-c

(c)-a

(d)-b

(e)-e

Step-by-step explanation:

(a) 3x+7=43

=3x=43-7

=3x=36

• x=12 (option d)

(b)4x-3=x+2

= 4x-x=2+3

=3x=5

• x=5/3(option c)

(c)5(2x+3)=-6(x-3)=47

=10x+15-6x+18=47

=4x+33=47

=4x=47-33

=4x=14

=x=14/4

• x= 7/2(option a)

(d)28/3=5+6(x+5)-7

=28/3=5+6x+30-7

=28/3=6x+28

=28/3-28=6x

=28-84/3=6x

=-56/3=6x

=-56/3×6=x

• -28/9=x (option b)

(e)x/5+4=32

=x+5=32-4

=x/5=28

=x=5×28

• x = 140 (option e)
