Answer: ( -1 , 3 )
Step-by-step explanation:
y = 5x + 8 ..........equation 1
y = -4x - 1 ............... equation 2
equating equation 1 and 2 , we have :
5x + 8 = - 4x - 1
collecting the like terms , we have
5x + 4x = -1 - 8
9x = -9
dividing through by 9 , we have
x = - 1
substitute x = -1 into equation 1 to find the value of y ,
y = 5x + 8
y = 5 (-1) + 8
y = - 5 + 8
y = 3
Therefore the solution to the system of linear equation is ( -1 , 3 )
