Simplify :
(y + 3) * 2 = (-1) * ( x - 4)

Answer 1

To simplify the left hand side, multiply each term inside the brackets by 2. Can you do that?

Answer 2

I think so but, i'm not sure about the right side, do I multiply the (-1) or (x - 4) by 2??

Answer 3

You don't need to apply 2 to the right hand side. Can we treat the right hand side separately?

Answer 4

yes, s o would the left side be , 2y + 6?

Answer 5

Good work! Now for the right hand side: ignore the brackets around -1, and multiply each term inside the right hand brackets by -1.

Answer 6

so it would be -1 and -4

Answer 7

2y+6=4-x

Answer 8

@cody_123 Do you want to carry on?

Answer 9

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

Answer 10

So now we have simplified to:
2y + 6 = 4 - x
The next step is to add x to the left hand and the right hand sides. Can you do that?

Answer 11

2y + x ?

Answer 12

yes

Answer 13

2y + 6 + x = 4 -x + x
This can be simplified and rearranged to:
x + 2y + 6 = 4
Now we need to subtract 6 from both left and right hand sides:
x + 2y + 6 - 6 = 4 - 6 ............(1)
Can you now simplify (1) to get the answer?

Answer 14

2y + x = 5 ?

Answer 15

x + 2y + 6 - 6 = 4 - 6 ............(1)
The left hand side becomes x + 2y, the reason being that 6 - 6 = 0.
So we now have:
x + 2y = 4 - 6 ...............(2)
Can you simplify the right hand side?
