Multiply 6 ten time by itself
6*6*6*6*6*6*6*6*6*6 which = 60,466,176
and 6 by itself four times
6*6*6*6 which = 1,296
Then divide 60,466,176 by 1,296
Answer: 46,656
Take -5x + y =13 and rearrange for y:
y=13+5x
Substitute into other equation for y:
-3x+3(13+5x)=3
Multiply out brackets:
-3x+39+15x=3
Simplify:
12x+39=3
Rearrange for x:
12x=-36
x=-3
Substitute back into y=13+5x:
y=13+5(-3)
y=13-15
y=-2
It’s 75! 65+40= 105 then 180-105= 75
