(3x)² + 10² + bx
(3x)² + 10² + bx
6/7Y - 18/28 =-15/14
First, let's get a common denominator
24/28Y - 18/28 =-30/28
Move your terms to isolate Y
24/28Y=-12/28
Multiply by 28 on both sides
24/Y=-12
Times both sides by Y, then divide by -12
24/-12=Y
Simplify
-2=Y
I hope this Helps!

Answer:
{x,y} = {1/3,1/9}
Step-by-step explanation:
Solution :
{x,y} = {1/3,1/9}
System of Linear Equations entered :
[1] 4x + 6y = 2
[2] -4x + 3y = -1
Graphic Representation of the Equations :
6y + 4x = 2 3y - 4x = -1
Solve by Substitution :
// Solve equation [2] for the variable y
[2] 3y = 4x - 1
[2] y = 4x/3 - 1/3
// Plug this in for variable y in equation [1]
[1] 4x + 6•(4x/3-1/3) = 2
[1] 12x = 4
// Solve equation [1] for the variable x
[1] 12x = 4
[1] x = 1/3
// By now we know this much :
x = 1/3
y = 4x/3-1/3
// Use the x value to solve for y
y = (4/3)(1/3)-1/3 = 1/9
Solution :
{x,y} = {1/3,1/9}
