4(x+5) = 4x +5x it's probably easy but i'm dumb
Irina18 [472]
<span>4(x+5) = 4x +5x

Simplify by distributing and combining like terms
</span>(4)(x)+(4)(5)=4x+5x
4x+20=4x+5x
4x+20=(4x+5x)
4x+20=9x

Subtract 9x from each side
4x+20−9x=9x−9x
5x+20=0
<span />
Subtract 20 from each side
−5x+20−20=0−20
−5x=−20

Divide each side by -5
-5x ÷ -5 = -20 ÷ -5
x = 4

P.S this was actually harder than most algebra problems, so don't beat yourself about it :D<span /><span /><span /><span /><span />
