Answer: 64/75 or .85333333
Step-by-step explanation:
2/5*8/15=16/75
16/75÷1/4=16/75*4/1
Because dividing by a number is the same as multiplying by the reciprocal
16/75*4/1=64/75
64/75=0.85333333
8x - 11y =78
2x - 2y = 12
8x - 11y = 78
-8x +8y = -48
-3y = 30
y= -10
2x + 20= 12
2x= -8
x= -4
(-4, -10)
