Question

solve the equation. ( x+1)+2y=30; ( y+3)+4x=56​

Answer 1

Answer:

$x + 1 + 2y = 30 \\ x + 2y = 29 \\ y + 3 + 4x = 56 \\ y + 4x = 53 \\ y = 53 - 4x \\ putting \: it \: in \: equation \: one \\ x + 2y = 29 \\ x + 2(53 - 4x) = 29 \\ x + 106 - 8x = 29 \\ 106 - 29 = 7x \\ 77 = 7x \\ x = 11 \\ y = 53 - 4x \\ y = 53 - 4 \times 11 \\ y = 53 - 44 \\ y = 9$
