How do i find the a in this equation : 5a+7=4a-3 ?

and please tell me how to work it out and whats the answer , i need it desperately

Answer 1

-20

Answer 2

5a + 7 = 4a - 3

-4a      = -4a     (subtract 4a from both sides)

-----------------------

a + 7   = -3      (result after subtracting from both sides)

-7        = -7      (subtract 7 from both sides of result)

----------------------

a         = -10    (result after subtracting from both sides of previous result)

Answer 3

5a - 4a = - 3 - 7

a = - 10

Answer 4

5a + 7 = 4a -3

5a -4a = -3 -7

a = -10

Answer 5

combine LIKE terms....

5a - 4a = -3 - 7

then...

a = -10

checking...

substitute the value of (a) to the original equation...

5(-10)+7=4(-10)-3

-50+7=-40-3

-43=-43

check!
