Respuesta :
A) y=-2x+19
B) y=x+7 Multiplying B) by -1
B) -y = -x -7 then adding it to A)
A) y = -2x + 19
3x = 12
x = 4
y = 11
B) y=x+7 Multiplying B) by -1
B) -y = -x -7 then adding it to A)
A) y = -2x + 19
3x = 12
x = 4
y = 11
Answer with Step-by-step explanation:
We are given a system of linear equations:
y= -2x+19
y=x+7
On equating the above system, we get
-2x+19=x+7
-2x-x= 7-19
-3x = -12
On dividing by -3 on both sides, we get
x=4
Putting x=4 in y=x+7, we get
y= 4+7
y= 11
Hence, Solution of the system of linear equation y= -2x+19 y=x+7 is:
x=4 and y=11
