If you go on Wolframalpha.com you can insert the equation in there and it will solve it for you. I inserted your equation and x is 5.

Distributive Property....

7(5 +9) = 7 . x + 7 . 9

35 + 45 = x + 58

80 = x + 85
x = -5

@SolomonZelman
did i do that right???

solomonzelman · Answer

no

solomonzelman · Answer

7(5+9)=7 * x + 7 * 9             

7 * 5 + 7 * 9 = 7 * x + 7 * 9

you should see already what x is equal to.
