Question

(x + 23) + (2x + 4) = 180 Find the value of ¨x¨

Answer 1

$(x+23)+(2x+4)=180$

$x+23+2x+4=180$

$3x+27=180$

$3x=180-27$

$3x=153 /: 3$

$x=51$

Answer 2

Answer:

x=51

Step-by-step explanation:

$(x + 23) + (2x + 4) = 180$

Ok, as you can see, we have + everywhere, so we don't need parenthesis.

$x + 23 + 2x + 4 = 180$

We need to count letters with letters and numbers with numbers

$x + 23 + 2x + 4 = 180\\ \\ 2x+27= 180$

Now it's simple, we have to izolate the unknown in the left side, and evrything go in the right side with the oppsite sign, unless it's already there. So 27 will turn in -27 and 180 will remaind exactly like this.

$3x+27= 180\\ \\ 3x=180-27 \\\\ 3x=153$

Divide all with 3

$3x=153 /3 \\\\ x=51$
