Step-by-step explanation:
Make ratios.
12/16: 15/x
cross multiply
12(x) = 12x
16(15) = 240
12x = 240
isolate the x, divide 12 from both sides
12x/12 = 240/12
x = 20

Answer:
x=2
Step-by-step explanation:
28−(3x+4)=2(x+6)+x
We need to use the distributive property for the right side.
28−3x−4=(2)(x)+(2)(6)+x)
28−3x−4=2x+2+x
−3x+24=3x+12
From here we need to subtract 3x from both side.
−3x+24−3x=3x+12−3x
6x+24=12
Transfer +24 on the right side.
6x=12−24
6x=−12
Finally, divide both sides by −6
6x/-6 = -12/-6
x=2
