$2x+4y=6\\\\ x+2y=3\\\\ x=-2y+3$

In order to isolate x, subtract 4y from both sides.

2x + 4y - (4y) = 6 - (4y)
2x = 6 - 4y

now, divide each side by 2 (or multiply by 1/2)

(1/2) * (2x) = (1/2) * (6-4y)
x = 3 - 2y

now that x is the only variable on the left side of the equation, you’ve successfully isolated x.

Sales of SUVs (sport utility vehicles) in the United States (in millions) for the years 1990-1999 can be modeled by the quad

Andrei [34K]

If x = 0 is 1990, x = 1 is 1991, then 1998 is represented by x = 8. Substitute this value of x into the quadratic equation to find y:
y = 0.016*(8^2) + 0.124*8 + 0.787 = 1.024 + 0.992 + 0.787 = 2.803
Therefore, there were approximately 2.803 million SUVs sold in 1998.
