Solve this by substitution

Mathematics
1 answer:

Answer:

y= 1 and x=-2

Step-by-step explanation:

Since they both equal y, you can equal them to each other:

x + 3 = 2x + 5

Then solve:

x - x + 3 = 2x - x + 5

3 - 5 = x + 5 - 5

-2 = x

Substitute x in either equation to solve for y:

y = (-2) +3

y = 1

Or the other equation:

y = 2(-2) + 5

y = -4 + 5

y = 1

hope this helps :)

How to <br> Swoop the decimal
ddd [48]

Answer:

Step-by-step explanation: I don’t really understand what this means, but I think it might. For multiplication of decimals, you would move the decimal point to the left. For division, you’d move the decimal point to the right.

Solve 0.5x^2+6x+5=0
Lelu [443]
I hope this helps you




x^2/2+12x/2+10/2=0




x^2+12x+10=0


ax^2+bx+c=0



disctirminant =b^2-4ac


x1,2=-b (-,+) square root of disctirminant /2a



a=1 b=12 c=10


disctirminant = 12^2-4.1.10=144-40=104


x1= -12+square root of 104/2


x2= -12- square root of 104/2
