Answer:

a) x = 5

b) x = 12

Step-by-step explanation:

x + 3 = 8

Subtract 3 on both sides.

x = 8 - 3

x = 5

x - 5 = 7

Add 5 on both sides.

x = 7 + 5

x = 12

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 )
