Solve -(4a - 7) - 5a = 10 + a?

Question

I need help! I've been doing this problem for a while and I can't figure it out.

Answer 1

This is how I would solve it:

First, distribute your -1 by multiplying "4a" and "-7" by "-1"; then you will get:

-4a + 7 - 5a= 10 + a

then add like terms:

-9a + 7 =10 + a

then, subtract the "a" from the right side of the equation to gather like terms:

-10a +7= 10

then subtract 7 from both sides:

-10a=3

then, divide by -10:

a=  - 3/10

Hope this helps.

Answer 2

- 4 a + 7 - 5 a = 10 + a

7 - 9 a = 10 + a

- 3 = 10 a

a = - 3 / 10

Answer 3

-(4a - 7) - 5a = 10 + a

-4a + 7 - 5a = 10 + a

-9a + 7 = 10 + a

-10a = 3

a = -3/10

Answer 4

-(4a-7)-5a=10+a          use the distributive property.

-4a+7-5a=10+a           - times 4a =-4a, then - times -7=+7.

-9a+7=10+a               add -4a+(-5a) which equals -9a.

+9a         +9a             add 9a to both sides.

7=10+10a                  simplify.

-10 -10                       subtract 10 from both sides.

-3=10a                        simplify.

-3/10=10a/10             divide both sides by 10.

-3/10=a                     simplify   a= -3/10.

Answer 5

-9a+7=10+a

-9a=3+a

-10a=3

a=-3/10

Answer 6

distribute the neg. sign:

-4a +7 -5a = 10 +a

combine like terms:

-9a+7=10+a

bring the "a" to one side and the 7 to the other:

-10a=3

divide by -10 to get a alone:

a=(-3/10)

Answer 7

-(4a-7) -5a = 10 + a

= (-4a+7) - 5a = 10 a

= 3a - 5a = 10a

= -2a = 10 a

-2            10a

___   =  ______

-2             -2a

= A = -5

therefore, A is equalled to -5.

I love Algebra! Thank You!

Answer 8

There are two different answers to your question so far.  Let's see if I can be a tie breaker.

-4a + 7 - 5a = 10 + a

-9a + 7 = 10 + a

add 9a to both sides

7 = 10 + 10a

-3 = 10a

a = -3/10 or -0.3

Answer 9

-(4a-7) - 5a = 10 + a

-4a + 7 - 5a = 10 + a

-9a + 7 = 10 + a

-a                  -a

-10a +7 = 10

        -7     -7

-10a = 3

a= -3/10

Answer 10

a = 2
