Question

how do you solve this problem... 5x + 2 (4+x) = 10

Answer 1

distributive property is like a(b+c) = ab + ac
so 2(4+x) = 8 + 2x
so 5x + 2(4+x) = 10
5x + 8 + 2x = 10

make sense so far? :)

Answer 2

then you can add 5x + 2x = 7x
so 5x + 8 + 2x = 10 becomes
7x + 8 = 10 then subtract 8 from both sides
-8 -8
7x = 2 then divide both sides by 2

Answer 3

@jigglypuff314 divide both sides by 7
7x/7=2/7
x=2/7

Answer 4

oh right, sorry ;)
