Solve both using linear system of equations please quick

2:

5 ( X + Y = 4 )

- 5X +2Y = -6 / Multiply first equation by 5 and add with second equation

0 X + 7Y = 14

Y = 2

Substitute Y=2 in the first equation , and solve for X

2 + X = 4

X = 2

Test:

2 + 2 =4

-5(2) + 2( 2) = -6

After writing your first equation properly , then solve it yourself by the same, elimination method.
