Let x^2+18x=44 . What values make an equivalent number sentence after completing the square?

Lostsunrise [7]

To find the final term to compete the square you need to divide the 'x' term by 2 then square it

$x^2 +18x + = 44+ \\ x^2+18x+( \frac{18}{2} )^2=44+( \frac{18}{2} )^2 \\ x^2+18x+9^2=44+9^2 \\ x^2+18x+81=44+81 \\ (x+9)^2=125$ - equivalent equation

Y=2x y=7x + 15 substitution

sergejj [24]

$y = 2x \\ y = 7x + 15$

Substitute the given value of y into the equation y=7x+15

$2x = 7x + 15$

Move the variable to the left-hand side and change its sign

$2x - 7x = 15$

Collect like terms

$- 5x = 15$

Divide both sides of the equation by -5

$x = - 3$

Substitute the given value of x into the equation y=2x

$y = 2 \times ( - 3)$

Solve the equation for y

$y = - 6$

The possible solution of the system is the ordered pair (x,y)

$(x,y) = ( - 3, - 6)$
