Answer:
By combining the equations they say
Step-by-step explanation:
-8x-5y=-13
-4x-5y= 11
so subtract lower from the upper :)
-8x-5y= -13
-(-4x-5y=11)
multiply by the negative sign
-8x-5y= -13
+4x +5y= -11
now do the operations of each
-4x +0 = -24
hmm looks easier now , huh
x= - 24 / -4
x= 6
plug x in to either equations and solve for y
-8(6)-5y= -13
-48 -5y= -13
-5y=35
y = - 35 / 5
y = - 7 : ) yay !!
