Solve for y

Andreas93 [3]

Answer:

y = 3

Step-by-step explanation:

2y - 3 = $\sqrt{3y^2-10y+12}$

square both sides to remove sqrt bracket

(2y - 3)^2 = ( $\sqrt{3y^2-10y+12}$ )^2

simplify both sides

(2y - 3)(2y - 3) = $3y^2$ - 10y + 12

$4y^2$ - 12y + 9 = $3y^2$ - 10y + 12

bring all value to left side

$y^2$ - 2y - 3 = 0

factor

(y - 3)(y + 1)

solve for y

y = 3, y = -1

When plugged back into the equation, only y = 3 is true

lana66690 [7]

$\text{Substitute the values of x and y to the equation}\\\\x=-2,\ y=6,\ 3ax+2by=6\\\\3a(-2)+2b(6)=6\\\\-6a+12b=6\qquad|\text{add 6a to both sides}\\\\12b=6a+6\qquad|\text{divide both sides by 12}\\\\b=\dfrac{6a}{12}+\dfrac{6}{12}\\\\\boxed{b=\dfrac{1}{2}a+\dfrac{1}{2}}$
