Answer:

i think you wrote the equation wrong because the answer is 106

Step-by-step explanation:

10+(1/2)4x48 solve using system of equations

multiplying is first (1/2)x4=2

10+2x48

multiply again 2x48=96

10+96=106

Hello , I need help please THANKYOU 100 POINTS
Gnesinka [82]

Step-by-step explanation:

1)

Let x=larger number

y=smaller number

x+y=59

x-y=13

Now adding these two equations we get

2x=72

x=36

Now as x-y=13

y=x-13=36-13=23

y=23

Therefore the larger number is 36 and the smaller number is 23

(or else u could also write)

The numbers are 36 and 23

---------------------------------------------

2)

Let x=first number

y=Second number

x+y=15

2x-y=6

Now adding these two equations we get

3x=21

x=7

Now as x+y=15,

y=15-x=15-7=8

y=8

Therefore the first number is 7 and the second number is 8

-------------------------------------------

3)

Let x=Larger number

y=smaller number

x-y=3

x-3y=-11

Now on subtracting these two equations we get

2y=14

y=7

Now as x-y=3,

x=y+3=7+3=10

x=10

Therefore the larger number is 10 and the smaller number is 7

Pls help stuck on big ideas math

Answer:

x = 15

Step-by-step explanation:

Substitute: -4/5x + 7 = -5

Rearrange unknown terms to the left side of the equation: -4/5x = -5 - 7

Calculate the sum or difference: -4/5x = -12

Divide both sides of the equation by the coefficient of variable: x = -12 × (-5/4)

Remove the parentheses: x = 12 × 5/4

Cross out the common factor: x = 3 × 5

Calculate the product or quotient: x = 15

So the answer is: x = 15

10. 2x + 7y = 1<br> 2x - 4y = 12<br> Solve for y
adoni [48]

Answer:

The solution for y = -1.

Step-by-step explanation:

Given:

2x\ +\ 7y\ =\ 1    ....(1)

2x\ -\ 4y\ =\ 12  ....(2)

So, to solve for y, first we solve for x in equation (2):

2x-4y=12

⇒2x=12+4y

Dividing both sides by 2,

⇒x=6+2y            

Now, substituting the value of x  in equation (1):

2x+7y=1

⇒2(6+2y)+7y=1

⇒12+4y+7y=1

⇒12+11y=1

⇒11y=1-12

⇒11y=-11

Dividing both sides by 11,

⇒y=-1

Therefore, the solution for y = -1.
