algebra problems, can you solve?

You do know there is an ENTER or RETURN key on your keyboard that will separate your information so that others can understand...

a=1/2 x=4 y= -2 5y-8a+6xy-7x= 10x(8a+-4y) +-3y= 6xy-2x (4a-8y)=

versus

a = 1/2

x = 4

y = -2

5y - 8a + 6xy - 7x =

10x(8a + - 4y) + -3y =

6xy - 2x (4a - 8y) =

To find the value of each expression, you must substitute the given values for a, x and y

Follow 'order of operations' and these are very simple. You can do it. You must do it.

Go for it. Can you solve ?

Go for it. Can you solve ? any way you got the following at last

-90-400+192=-298

the way you have written it seems like you are running away from math subconscioulsy. please take more effort in being clear. we will be happy to help

math is fun

You can too, use your pencil and write the sentence using the values given. Then use the calculator and do the math. Simple!
