Answer:
d) x = 2
Step-by-step explanation:
3(x - 6) + 3 = -9
<em>open the parenthesis</em>
3x - 18 + 3 = -9
3x - 15 = -9
<em>add 15 to both sides of the equation</em>
3x - 15 + 15 = - 9 + 15
3x = -9 + 15
3x = 6
<em>divide both sides by 3</em>
3x/3 = 6/3
x = 6/3
x = 2
Answer:83
Step-by-step explanation: A triangle is 180 degrees in total so if you take 90+45=135 then you subtract 52 from 135 and you get 83
so x=83
<span>5(x+1)= 4(x-1)+x
5x + 5 = 4x - 4 + x
5x +5 = 5x -4
5 </span>≠<span> -4
x </span>∈ ∅
