Question

How to solve 12x+9y=15

Answer 1

I have algebra caculator and I used it to solve this problem.

Answer 2

Can I get brainliest. Your answer is Step 1 :

Pulling out like terms :

1.1 Pull out like factors :

12x + 9y - 15 = 3 • (4x + 3y - 5)

Equation at the end of step 1 :

Step 2 :

Equations which are never true :

2.1 Solve : 3 = 0

This equation has no solution.
A a non-zero constant never equals zero.

Equation of a Straight Line

2.2 Solve 4x+3y-5 = 0

Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line 4x+3y-5 = 0 and calculate its properties
