As the equation plainly tells us, "Wye is equal to two eks plus four".
The value of 'y' completely depends on the value of 'x'. Whenever 'x' changes,
the value of (2x + 4) changes instantly.
It equals to the equation of a straight line.
2x must equal 12 so x is 6.
It's not an equation and therefore unsolvable until it equals something.
-2x plus 3y equals 1
To solve for x, set up the equation: 2x +2x = 40 (then simplify) 4x = 40 (then divide both sides of the equation by 4) x = 10 (this is the answer)
No. It is a meaningless equation. You may have intended to say: 2 times the sum of x and g is equal to 2x plus 2g.
y = 2x + 1 IS a linear equation!
4
21
It is an equation and the value of x is 1
Yes it is. The thing that makes it a quadratic equation is that "x squared" in there.
Multiply the first equation by 3 to give 9x + 15y = 21
