Answer:
x = 3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5(x−3)+2x+21=3(x+4)+2x
(5)(x)+(5)(−3)+2x+21=(3)(x)+(3)(4)+2x(Distribute)
5x+−15+2x+21=3x+12+2x
(5x+2x)+(−15+21)=(3x+2x)+(12)(Combine Like Terms)
7x+6=5x+12
7x+6=5x+12
Step 2: Subtract 5x from both sides.
7x+6−5x=5x+12−5x
2x+6=12
Step 3: Subtract 6 from both sides.
2x+6−6=12−6
2x=6
Step 4: Divide both sides by 2.
Hope this helps!

Answer: $8.20
Step-by-step explanation:
Answer:
18
Step-by-step explanation:
Hello
The number is more by three than a multiple of of 5 (i.e 5x +3) and more than 2 than a multiple of 4 (ie 4y+2(
Now 5x+3=4y+2
ie 5x +1 =4y
we need to give the lowest pair of values to x and y such that the last equality is satisfied.
By trial, x = 3 and y = 4
thus the number is 5x+3 =5(3)+3 =18=4y+2 =4(4)+2=18
I hope it has helped you.
