7x-3=-3+7x i neep help answer this please
erica [24]

Answer:

All real numbers are solutions.

Step-by-step explanation:

Let's solve your equation step-by-step.

7x− 3 = − 3 + 7x

Step 1: Simplify both sides of the equation.

7x − 3 = −3 + 7x

7x + −3 = −3 + 7x

7x − 3 = 7x − 3

Step 2: Subtract 7x from both sides.

7x− 3 −7x = 7x −3 −7x

−3 = −3

Step 3: Add 3 to both sides.

−3 + 3 = −3 + 3

0 =  0

Two apples and three peaches cost $1.65. three apples and two peaches cost $1.60. what is the cost of one peach
marta [7]
Apples = $.30
Peaches = $.60

You can get this by setting up a system of equations that looks like this. 

2x + 3y = 1.65
3x + 2y = 1.60

Where x is the amount of apples and y is the number of peaches. Then you can solve using any of the methods (I would suggest elimination for ease).
