Question

If x=3 then solve the equation: y=10x×10x-7×-12

Answer 1

First put in the value of X into all the X's. So 10(3) times 10(3) minus 7 times -12. Then simplify, 10(3)= 30. then your equation would turn out like this 30×30×-7×-12. After that multiply first then Subtract, 30×30=90 and -7×-12=84. then you have 90+84 left and then add them together and you get 174.

Answer 2

The answer is y = 545.
