The equation of a line is y = mx + b. The variable m is the slope, so m = 2/3, giving you the equation y = (2/3)x + b. To find b (the y-intercept), plug in the given x and y values. So, it'll look like this: (-3) = (2/3)(7) + b. Finally, solve algebraically for b:
Multiply 2/3 by 7.
-3 = 14/3 + b
Subtract 14/3 from both sides.
-23/3 = b
The final equation is y = (2/3)x - 23/3.
5x-40=3x+8
Add 40 to both sides
5x=3x+48
Subtract 3x from both sides
2x=48
Divide by two on both sides
X=24
To solve this, first subtract 6x from both sides.
That is because there cannot be the same variable on both sides of the equation. The new equation would be:
6x=24
Now divide by both sides of the equation by 6
x=4
