Question

Solve the equations.
Who solve this correct answer in full detail step by step. I will make him/her Brain list answer. ​

Answer 1

Answer:

5. i) 2

2.) 8

3) 25

4) it's hard i don't know

5) -1

6) 20

6. i) 18

ii) -5

Step-by-step explanation:

1) 4x-3x=15-13

x=2

2) 9x-7x=15+1

2x=16

x= 16/2 = 8

3) 2x-7=x+18 (transposed RHS TO LHS AND LHS TO RHS)

= 2x-x=18+7

= x= 25

5) 8x+4=3x-3+2

= 8x-3x= -4-3+2

= 5x= -7+2

x= 5/-5

x= -1

6) 3x-10=5x-50

= -5x+3x = -50+10

= -2x = -40

= x= -40/-2 = 20 (minus and minus cuts)

6. 1) x/2 - x/3 =2+1

= 3x-2x/6 = 3

= x/6 =3

x= 6×3

x= 18

ii) 5x-3x/2 = -7/2 -14

= 10x-3x/2 = -7-28/2

= 7x/2= -35/2

=7x × 2 = -35×2

=14 x = - 70

= x = -70/14

=x = -5

i hope this helped
