Question

i) The number of solutions to a linear equation is ___


(ii) 2(x - 4) = 6 then x is -----------



(iii) Solution of |3x + 4| = −9 is ----------

Answer 1

Answer:

1

$x = 7 \\ x - 4 = \frac{6}{2} \\ x - 4 = 3 \\ x = 3 + 4$

2nd one

$3x = - 9 - 4 \\ 3x = - 13 \\ x = \frac{ - 13}{3} \\ x = \frac{ - 13}{3}$

which is 4.33333 its recurring

Answer 2

Answer:

the number of solution to a linear equation is one.

2(x-4)=6

2x-8=6

2x=6+8

2x=14

x=14/2

x=7

I3x+4I=-9

THERE ARE TWO POSSIBILITIES

3x+4=-9                                  or              3x+4=9

3x=-9-4                                  or                    3x=9-4

3x=-13                                  or                      3x=5

x=-13/3                                  or                           x=5/3

solution set ={-13/3,5/3}

i hope this will help you :)
