X+2y=17
8x+3y=45
answer fast

Answer fast? What?

x + 2y = 17...Equation A

8x + 3y = 45...Equation B

Solve A for x.

x = 17 - 2y

Plug this into B to solve for y.

8(17 - 2y) + 3y = 45

136 - 16y + 3y = 45

136 - 13y = 45

-13y = 45 - 136

-13y = -91

y = -91/-13

y = 91/13

y = 7

To find y, plug x = 7 into either equation to find x.

I will use Equation A.

x + 2y = 17

x + 2(7) = 17

x + 14 = 17

x = 17 - 14

x = 3

x = 3, y = 7

£56

step-by-step explanation:

u divide 24 by 3 and u get 8 so if u do 8 time 7 or 8+8+8+8+8+8+8 u get 56 and 56 divided by 7 is 8.
