Question

Solve by elimination
{10x-4y=-6
{-3x+4y=-1
WORK MUST BE SHOWN

Answer 1

x = -1

y = -1

Explanation:

10x - 4y = -6 ---------------------(I)

-3x + 4y = -1 ---------------------(II)

Add equation (I) & (II) and y will be eliminated.

10x - 4y = - 6

-3x + 4y = -1 {Add}

7x = - 7

x = -7/7

x = -1

Plugin x =-1 in equation (I)

10*(-1) - 4y = -6

-10 - 4y = -6 {Add 10 to both sides}

-4y = -6 + 10

-4y = 4 {Divide both sides by (-4)}

y = 4/(-4)

y = -1
