The standard form is Ax + By = C
Given the linear equation, y = x + 10, we must transpose x to the left-hand side of the equation:
- x + y = x — x + 10
- x + y = 10
Next, we must multiply both sides by (-1) because A must be positive:
(-1) (- x + y) = 10 (-1)
This leads to:
x — y = -10 in standard form, Ax + By = C
Answer:
x = 8, y = 3
Step-by-step explanation:
3x - 12y = 60
x + 2y = 14
3x - 12y = 60
3x + 6y = 42 (multiply by 3 so the x is the same as the top equation)
6y = 18 (subtract the equations)
y = 18 / 6
= 3
To find x, substitute y into the 2nd equation since it is the simplest so:
x + 2(3) = 14
x + 6 = 14
x = 14 - 6
= 8
A and C should be the answer, hope this helps
