Answer 1

Answer:

a)

5x-3=12+8x

5x-8x=12+3

-3x=15

x=-5:- ANSWER

b) 5(x+43)=2(3x+4)

5x+215=6x+8

5x-6x=8-215

-x=-207

x=207:-ANSWER

Answer 2

Answer:

a) x=3.

b) x=207.

Step-by-step explanation:

a) 5x-3=12

5x=12+3 the sigh has been changed because 3 had gone to the right hand side.

5x=15

x=15/5

x=3

b) 5(x+43)=2(3x+4)

5(x+43)

we have to multiply 5 with x and 43.

5x+215.

Now, 2(3x+4)

we have to multiply 2 with 3x and 4.

6x+8

result:

5x+215=6x+8.

5x-6x=-215+8

x=207
