Answer:
x=90
Step-by-step explanation:
First, it would help to make it so that the x's are not next to fractions. To do this, you can multiply all terms in the equation by 45. 45 is the closest common factor of 9 and 5, the denominators of the fractions. The answer would be;
20x+9x=2610
Then solve.
29x=2610
x=90
4 + y = -36
Subtract 4 on both sides
y = -36 - 4
y = -1(36+4)
y = -1(40)
y = -40
0.18 = 18/100
Simplfy 18/100 and you get 9/50
