I need to show work and Idk how for 2 or 3. The -5,-2 and 8,3 is the answers just need work shown thanks

#2
2x - 4y = -2
2x + 3y = -16
------------------subtract
-7y = 14
y = 14/-7
y = -2

2x - 4y = -2
2x - 4(-2) = -2
2x + 8 = -2
2x = -2 -8
2x = -10
x = -10/2
x = -5
answer x = -2 and y = -5

check:

2(-5)- 4(-2) = -2
-10 +8 = -2
-2 = -2.....true

2x + 3y = -16
2(-5)+3(-2) = -16
-10 + (-6) = -16
-16 = -16...true

X+2y=8 x-2y=-4 solve by system of equations
Vsevolod [243]

Answer:

Step-by-step explanation:

x + 2y = 8 -----------(I)

x - 2y  = -4 -----------(II)

Add equation (I) & (II) and thus y will be eliminated and we can get the value of 'x'

(I)           x + 2y = 8

(II)          <u>x - 2y  = -4</u><u>      </u>{Now add}

           2x         = 4

                   x   = 4/2

x = 2

Substitute x =  2 in equation (I)

2 + 2y = 8

    2y = 8 - 2

    2y = 6

      y = 6/2

y = 3
