Вычисли корень уравнения:

0,7+8+(−1,07t)=−11+0,7−1,57t

СРОЧНО!

Answer 1

$0,7+8+(-1,07t)=-11+0,7-1,57t\\8-1,07t=-11-1,57t\\-1,07t+1,57t=-11-8\\0,5t=-19\\t=-38$

Answer 2

Объяснение:

$0.7 + 8 + ( - 1.07t) = - 11 + 0.7 - 1.57t \\8 - 1.07t = - 11 - 1.57t \\ 8 - 1.07t + 1.57t = - 11 \\ - 1.07t + 1.57t = - 11 - 8 \\ 0.5t = - 11 - 8 \\ 0.5t = 19 \div 0.5 \\ t = - 38$
