The answer is x=3 I am pretty sure
Answer:
0 = 0
Step-by-step explanation:
2(x+4) = 4x + 3 - 2x + 5
Distribute
2 ( x + 4 ) = 4x + 3 - 2x + 5
2x + 8 = 4x + 3 - 2x + 5
Add the numbers
2x + 8 = 4x + 3 - 2x + 5
2x + 8 = 4x + 8 - 2x
Combine like trems
2x + 8 = 4x + 8 - 2x
2x + 8 = 2x + 8
Subtract 8 from both sides of the equation
2x + 8 = 2x + 8
2x + 8 - 8 = 2x + 8 - 8
Simplify
Subtract the numbers
2x = 2x
Subtract 2x from both sides of the equation
2x = 2x
2x - 2x = 2x - 2x
Simplify
Combine like terms
0=0
Result
0 = 0

Let “x” represent the cost of the dryer in dollars The washer costs 3x dollars 3x + x = 1000 4x = 1000 x = 250 The dryer is $250
X+y=15 0.3x+0.6y=0.4*15=6 solve the system of equation. Multiply equation one by 0.3: 0.3x+0.3y=4.5 subtract the new from the second equation: 0.3y=1.5 y=5 x=10
