Question

решите пожалуйста мне очень срочно !!

Answer 1

$2)10(5x + 2) - 45 = 36(33 + 2x) \\ - 25(1 - 11x) \\ 50x + 20 - 45 = 1188 + 72x \\ - 25 + 275x$

$50x - 25 = 1163 + 347x \\ 50x - 25 - 1163 - 347x = 0 \\ - 297x - 1188 = 0 \\ - 297x = 1188 \\ x = - 4$

$4)80(x - 4) + 15(3x + 13) = \\ 72(2x - 3) - 840 \\ 80x - 320 + 45x + 195 = \\ 144x - 216 - 840$

$125x - 125 = 144x - 1056 \\ 125x - 125 - 144x + 1056 = 0 \\ - 19x + 931 = 0 \\ x = 49$
