I am so confused, does anyone know how to solve 6x + 5y = 15.
PlEaSe HeLp
Solve for ?
Solving for x,
6x + 5y = 15
6x = 15 - 5y
x = (15 - 5y)/6
Solving for y,
6x + 5y = 15
5y = 15 - 6x
y = (15 - 6x)/5
thankss you sosososo much(:
You're welcome :)
Of course! I can help you solve the equation 6x + 5y = 15. This equation is in standard form, which is Ax + By = C, where A, B, and C are constants.
To solve this equation, we have a few options. One common method is to use the substitution method.
1. Solve for one variable in terms of the other variable in one of the equations. Let's solve for x in terms of y:
6x = 15 - 5y
x = (15 - 5y) / 6
2. Substitute the expression for x in the other equation. Replace x in the equation 6x + 5y = 15 with the expression we found in step 1:
6((15 - 5y) / 6) + 5y = 15
3. Simplify the equation by performing the necessary operations:
(15 - 5y) + 5y = 15
15 - 5y + 5y = 15
15 = 15
The equation 15 = 15 is always true, which means that this equation has infinitely many solutions. Geometrically, this equation represents a straight line in a coordinate plane. Any point (x, y) that satisfies this equation lies on that line.
So, in conclusion, the equation 6x + 5y = 15 has infinitely many solutions.
