4x + 7y = 1 ⇒ 12x + 21y = 3
3x + 10y = 15 ⇒ <u>12x + 40y = 60</u>
<u>-19y</u> = <u>-57</u>
-19 -19
y = 3
4x + 7(3) = 1
4x + 21 = 1
<u> - 21 - 21</u>
<u>4x</u> = <u>-20</u>
4 4
x = -5
(x, y) = (-5, 3)
(8^2)^-4 = 1/8^8
answer
C-1 over 8 times 8 times 8 times 8 times 8 times 8 times 8 times 8
First of all what are u using for brainly phone or laptop,computer. if computer or laptop go here and post it
