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!

In solving this type of problem always look for the person you don't have any information about in this case it's Eve therefore Eve is X, Justin has $7.50 more than Eve, therefore
X+$7.50 is Justin and Emma has $12 less than Justin, therefore subtract $12 from Justin X+$7.50-$12, since the total amount is $63 add all the numbers and equal them to $63.
x+7+x+7.5-12+ x=63
3x+3=63
3x=60
x=20
Plug in the x for each person
therefore Eve=$20
Justin=$20+$7.50= $27.50
Emma has $12 less than Justin therefore $15.50
Add all the money and it equals $63
Answer:
Step-by-step explanation:
5(X+2) = 5x +10 +10 5x=10-10=-20
-20/5= -4
