Question

3x+10+70=180 I'm supposed to find the value of x

Answer 1

To find the value of x let's make the situation a bit easier

3x+10+70=180
3x+80=180
3x=180-80
3x=100
x = about 33.33

Answer 2

$3x + 10 + 70 = 180 \\ 3x + 80 = 180 \\ 3x = 180 - 80 \\ 3x = 100 \\ x = \frac{100}{3} \\ x = 33.33$

Hope this helps!
