Answer:
Explanation:
i am assuming that it wants you to find x so here is what i got.
I reccomend drawing it out
(3) 25+16÷4x= 13(x-1)
its in this formate because HI + IG will give you HG
25+4x=13x-13
25+13=13x-4x (moved the X's so they can be suptracted)
38=9x
38÷9 = 9x÷9
x≈4.2
same thing goes for the rest
(4) 16x-19+12x+9=0
16x+12x-19+9=0
28x-10=0
28x=-10/28
x= 5/14
(5) 18x-2-7x+3=0
18x-7x-2+3=0
11x-1=0
11x=1
x= 1/11
