Answer:
y=-
x+3
Step-by-step explanation:
Expression (non-algebraic): 3+2
An equation: 2x +1 = 21
An inequality: 2x > 2+2
I just learned about it. Simple!
6x=5x+7
Subtract 5x from both sides.
-5x -5x
You end up with
1x=7 or x=7
Answer:
2x^2 -3x +10
Step-by-step explanation:
2(x^2 + 5) − 3(x + 1) + 3
Distribute
2x^2 +10 -3x -3 +3
Combine like terms
2x^2 -3x +10 -3+3
2x^2 -3x +10
2(4x - 5) = 49
8x - 10 = 49
8x - 10 + 10 = 49 + 10
8x = 59
8x/8 = 59/8
x = 7.375
