The answer is B.
∴Explanation
3 bags of apples and 2 pounds of grapes,
1 bag of apple equals with 4 pounds of grapes

1) We first multiply the 3 bags of apples with the 4 pounds that one bag equals with.
2) Then we add to the product in order to find the total pounds.

1] 3 x 4 = 12
2] 12 + 2 =14

Therefore the answer is B.

You want to solve for x first:
x+4-3=1 (combine 4 and -3)
x+1=1 (subtract 1 on both sides)
x=0

Solve the system of equation 2x + y = -4 and 5x – 3y = 1 by the method of elimination

Radda [10]

Step-by-step explanation:

first step while implementing the elimination method is to look at the numbers which can be multiplied to which in order to have like terms as solved below

as you can see in equation number 2 that the number three can be multiplied with equation 1 in order to have like terms so you can cancel them out

so , multiply 3 with the whole of equation 1

3( 2x + y = -4 )

= 6x + 3y = -12

( keep in mind the sign of the number)

5x -3 y = 1

now ,

we have

6x + 3y = -12

5x -3y = 1

as you can see that now we have like terms and when we add both these equations the like terms cancel out each other as they have opposite signs ( + - gives you - )

so , once you add the like terms this is what you will get

6x + 5x +3y-3y -12+1

= 11x + 0 - 11

then you can simplify this further for x first

11x = 11

x = 11/11

x = 1

now we have the value of x let's simply further for y

let's take equation 2

5(1) - 3y =1

5 -3y = 1

5-1 = 3y
