Question

Solve the equations and show how you solve for them

6x-3=11
15=x/3+2
-4(x-1)=7(x+4)
3(2x+1)=6x

Answer 1

Explanation:

1)

6x-3=11

6x=11+3

6x=14

x=2.33

2)

15=x/3+2

-2+15=x/3

13=x/3

x=31

3)

-4(x-1)=7(x+4)

-4x+4=7x+28

-4x-7x=-4+28

3x=24

x=8

4)

3(2x+11)=6x

6x+33=6x

33=-6x+6x

no solution

Answer 2

Explanation:

• 6x-3=11
• 6x=11+3
• 6x=14
• x=14/3
• x=2.33

• 15=x/3+2
• 15-2=x/3
• 13=x/3
• x=13×3
• x=39

• -4(x-1)=7(x+4)
• -4x+1=7x+28
• -4x-7x=28-1
• -11x=27
• x=27/-11
• x=2.45

• 3(2x+1)=6x
• 6x+1=6x
• 6x-6x=1
• No solution
