x= 1

Explanation:

64x + 2(-9 - 7) = 32

64x + 2(-16) =32 -> the 9 and 7 are both negatives, which caused the -16.

64x-32=32 -> the 2 and -16 were multiplied to create -32

64x=64 -> the -32 was added to the right to create 64.

x=1

In order to make sure it all makes sense, plug in the 1 for x, and see if it all equals 32 on both sides.

64(1) +2 (-9 - 7) =32

64 + 2 (-16) =32

64 -32 = 32

32=32

It all seems to check out perfectly fine.

x=1

Explanation:

64x+2(-9-7)=32

First, simplify the bracketed terms:

64x+2x(-16)=32

Then multiply out the left side:

64x-32x=32

Simplify addition and subtraction:

32x=32

Therefore,

x=1
