7x-(x-y) = 7x - x + y = 6x + y

9a-(2b-a) = 9a+a-2b = 10a-2b

hope it helped

Since there's a - next to the bracket, you minus everything inside of it, if there's a minus in the bracket, it turns to +
7x-(x-y) = 7x-x+y = 6x+y
9a-(2b-a) = 9a-2b+a = 10a-2b

2x+3y=19 // 6x+2y=22​
zvonat [6]

Answer:

(2, 5 )

Step-by-step explanation:

Given the 2 equations

2x + 3y = 19 → (1)

6x + 2y = 22 → (2)

Multiplying (1) by - 3 and adding to (2) will eliminate the x- term

- 6x - 9y = - 57 → (3)

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

0 - 7y = - 35

- 7y = - 35 ( divide both sides by - 7 )

y = 5

Substitute y = 5 into either of the 2 equations and solve for x

Substituting into (1)

2x + 3(5) = 19

2x + 15 = 19 ( subtract 15 from both sides )

2x = 4 ( divide both sides by 2 )

x = 2

solution is (2, 5 )
