-8(2a-3b) -5(6b) -5(-4a)
= -16a+ 24b -30b+ 20a (distributive property)
= (-16a+ 20a)+ (24b -30b)
= 4a -6b

The final answer is 4a-6b~

-8(2a-3b)-5(6b)-5(-4a) \\ (-8*2a)+(-8*-3b)+(-5*6b)+(-5*-4a) \\ (-16a)+(24b)+(-30b)+(20a) \\ (20a-16a)+(24b-30b) \\ (4a)+(-6b) \\ 4a-6b
The answer is 4a-6b, which can also be written 2(2a-3b).

Hope this helps!

1/2(2g-3)=-4(g+1) show work
brilliants [131]
1g-1.5=-4g-4 (distribute 1/2 and -4 inside their respective parenthesis)
1g=-4g-2.5 (add 1.5 to -4)
5g=-2.5 (add 4g to 1g)
g=-0.5 (divide both sides by 5)

What dose this equal 2(6x-4)=3(6x+2)
AveGali [126]

Answer:

-7/3

Step-by-step explanation:

2(6−4)=3(6+2)

2(6x-4)=3(6x+2)

Solve

1

Distribute

2(6−4)=3(6+2)

{\color{#c92786}{2(6x-4)}}=3(6x+2)

12−8=3(6+2)

{\color{#c92786}{12x-8}}=3(6x+2)

2

Distribute

12−8=3(6+2)

12x-8={\color{#c92786}{3(6x+2)}}

12−8=18+6

12x-8={\color{#c92786}{18x+6}}

3

Add

8

8

to both sides of the equation

12−8=18+6

12x-8=18x+6

12−8+8=18+6+8

12x-8+{\color{#c92786}{8}}=18x+6+{\color{#c92786}{8}}
