Which is the solution to the system 3x+y=8 and 7x−4y=25
tatyana61 [14]

Answer:

(3, - 1 )

Step-by-step explanation:

Given the 2 equations

3x + y = 8 → (1)

7x - 4y = 25 → (2)

Multiplying (1) by 4 and adding to (2) will eliminate the y- term

12x + 4y = 32 → (3)

Add (2) and (3)  term by term to eliminate y

19x + 0 = 57

19x = 57 ( divide both sides by 19 )

x = 3

Substitute x = 3 into either of the 2 equations and solve for y

Substituting into (1)

3(3) + y = 8

9 + y = 8 ( subtract 9 from both sides )

y = - 1

solution is (3, - 1 )

Drag the correct steps into order to solve the equation -3x – 6 = 18 for x.
BlackZzzverrR [31]

- 3x - 6 = 18

      + 6    + 6

-3x = 24

Divide both sides by -3

-3x/-3 = 24/-3

x = - 8
