The correct answer is x=3
Answer:
Step-by-step explanation:
The price is x
50% of the price is $35
- x*0.5 = 35
- x = 35/0.5
- x = 70
Answer is $70
y=-5/28,x=4
do the process of cancellation, if you wanna find the x pair just substitute y for 0 then answer. repeat for y.
ex:
7x-5(0)=28
7x=28
divide 28 by 7
x=4
___________
7(0)-5y=28
-5y=28
divide 28 by -5
y=-28/5
A decimal problem may be a addition problem you would need to regroup the hundredths to solve, like a money problem
