Let x be the number of households with TV.
So .68x would be the number of households with cable.
If 8000 were added to the above number, it would be equal to 67,600,000.
Thus we have our equation:
.68x + 8000 = 67600000
Solving for x:
.68x = 67592000
x = 99,400,000
Let the supplement be s.
180=s+115 => s=180-115= 65 degrees
Answer: X=7
Step-by-step explanation:Let's solve your equation step-by-step.
3x+8−x=4−2x+32
Step 1: Simplify both sides of the equation.
3x+8−x=4−2x+32
3x+8+−x=4+−2x+32
(3x+−x)+(8)=(−2x)+(4+32)(Combine Like Terms)
2x+8=−2x+36
2x+8=−2x+36
Step 2: Add 2x to both sides.
2x+8+2x=−2x+36+2x
4x+8=36
Step 3: Subtract 8 from both sides.
4x+8−8=36−8
4x=28
Step 4: Divide both sides by 4.
4x
=28
4x/4=x 28/4
=
28
/4=7
