Respuesta :
4.8(9−x)+36=102−2.5(2x+2)
First we will expand the equation by removing those parenthesis. We can use the distributive property. An example is 4.8(9-x) is 43.2-4.8x
43.2-4.8x+36 = 102-5x-5
Then we simplify each side by combining like terms.
79.2-4.8x=97-5x
Then to isolate the variable, we will subtract 79.2 on both sides.
-4.8x=17.8-5x
Then add 5x on both sides
0.2x=17.8
Finally, divide both sides by 0.2 and you get
x=89
Answer:
x =89
Step-by-step explanation:
4.8(9-x)+36=102-2.5(2x+2)
Distribute
43.2 - 4.8x + 36 = 102 - 5x -5
Combine like terms
79.2 -4.8x = 97-5x
Add 5x to each side
79.2 -4.8x+5x = 97-5x+5x
79.2 + .2x = 97
Subtract 79.2 from each side
79.2 -79.2+ .2x = 97-79.2
.2x =17.8
Divide by .2
.2x/.2 = 17.8/.2
x =89
