Question

1. 3X-2+X=14
2. 2+3(A-1)=8

Answer 1

Answer:

a. x 4

b a 3

Step-by-step explanation:

3X-2+X=14

x= 4

2+3(A-1)=8

a= 3

Answer 2

Answer:

1=4

Step-by-step explanation:

3x -2+x=14     like term are colected

3x+x-2=14 then  

4x=14+2  b/c  when the - go thruth =sine it will be + sine then

4x=16   and to make x alone

4x =16

4      4       so 4 over 4 slaped then

x =16/4 =4

#2,  2+3(a-1)=8  now 2+3=5so

5(a-1)=8   then multiply 5 with both a and 1

5a-5=8  now like term is colleceted so

5a=8+8

5a=16  so

5a =16            5/5 is slaped then one one times a =a then

5      5  

a=16/5   so a =3.2
