<h3>I'll teach you how to solve 2x + 9 = -27</h3>
-----------------------------------------------------
2x + 9 = -27
Subtract 9 from both sides:
2x+9-9 = -27-9
SImplify:
2x=-36
Divide both sides by 2:
2x/2 = -36/2
Simplify:
x= -18
Your Answer Is x= -18
plz mark me as brainliest if this helped :)
Generally, x <span>• x is accepted to mean "x times x" or "x multiplied by x"
and x+x means "x plus x" or "x added to x"
let's try by subsituting numbers for them
if we can find one case where the statement "x+x is the same as x</span><span>•x" is false, then it is not true
let's try x=4
x+x=x</span><span>•x
4+4=4</span>•<span>4
8=16
false
so it is not true
(x+x is equal to 2x, so therefor if we were to solve 2x=x</span><span>•x, we would get that it is only true for x=2 and x=0)
it is not always true

3 = q/11....multiply both sides by 11, this cancels out the 11's on the right
11 * 3 = q
33 = q
Answer:
Odd integers are always one more that an even integer:
1st: 2n+1
2nd: 2n+3
Step-by-step explanation:
14n+7 = 10n+15
4n = 8
n = 2
------------
1st: 2n+1 = 5
2nd: 2n+3 = 7
7x=5*(x+2)
7x=5x+10
7x-5x=10
2x=10
x=5
