6x+7y=45 9x-7y=45 x=? y=?

Simply eliminate y to get the value of x (Because 7y-7y=0 which is easier to get the answer and faster)

15x=90 is from 6x+9x = 15x, 7y-7y = 0 and 45+45 = 90

We know the value of x, now for the value of y.

Substitute x = 6 into one of the equation, any equations but not all, just one.

So for me, I'll substitute x=6 in 6x+7y=45

So the answer is x = 6 and y = 9/7

(8+64)^2= 5184 < answer

step-by-step explanation:

2^3 = 8

4^3= 64

(8+64)^2 = 5184
