The answer going to be A: they will be orthogonal if and are orthogonal
All you have to do is add the number to the variable you need to. It works the same for subtraction instead you will put y-14 or any variable and number that is needed to subtract from it and remember when they say a number more than a variable it is + that number if they say a number less than a variable it is - that number .
y+14
The answer would be D.-13/21
Multiplication property of equality (Multiply both sides by 2)
9(8 - x) + 72 = 204 - 5(3x + 24)
Distributive property
72 - 9x + 72 = 204 - 7.5x - 60
Combine like terms
-9x + 144 = -7.5x + 144
Subtraction property of equality (Subtract both sides by 144)
-9x ≠ 7.5x
No solution
