Answer:
One solution
Step-by-step explanation:
Let's solve your equation step-by-step.
p+9=2p−3
Step 1: Subtract 2p from both sides.
p+9−2p=2p−3−2p
−p+9=−3
Step 2: Subtract 9 from both sides.
−p+9−9=−3−9
−p=−12
Step 3: Divide both sides by -1.
−p
−1
=
−12
−1
p=12
Answer:
p=12
Answer:
x = -8
Step-by-step explanation:
y = 3x + 14
2x - 3y = -14
So, what is the substitution? Y of course, this is because y is equal to 3x + 14.
2x - 3 (3x + 14) = -14
Multiply 3 with the numbers in the parentheses.
2x - 9x + 42 = -14
So you maybe be wondering why it is a negative 7 instead of subtracting 9 with 2. Using PEMDAS, we always read from left to right. So it is basically 2 -9 and you get -7.
-7x + 42 = -14
Then subtract 42 from both sides.
-7x + 42 - 42 = -14 - 42
Simplify
-7x = -56
Divide 7 by both sides.
-7x / 7 = -56 / 7
x = -8
And you might ask, why we get x instead afterwards. This is because both -7 and 7 cancel each other out leaving us with x.
The answer is 1.6 Hope this helps!!
