Answer:
8 times 5 is 40
8 plus 32 is 40
21 divided by 3 is 7
21 minus 14 is 7
E makes no sense becayse you cant multiply 21 by anything to get 7
Step-by-step explanation:
There are two ways to do this but the way I prefer is to make one of the equations in terms of one variable and then 'plug this in' to the second equation. I will demonstrate
Look at equation 1,

this can quite easily be manipulated to show

.
Then because there is a y in the second equation (and both equations are simultaneous) we can 'plug in' our new equation where y is in the second one

which can then be solved for x since there is only one variable

and then with our x solution we can work out our y solution by using the equation we manipulated

.
So the solution to these equations is x=-2 when y=6
