Question

Решите уравнения а) 15-(3x-3)=5-4x б) 4*(x-0.5)-2*(x+0.8)=-2.6

Answer 1

А) 15-(3x-3)=5-4x
15-3х+3=5-4х
-3х+4х=5-15-3
х=-13
б) 4*(x-0.5)-2*(x+0.8)=-2.6
4х-2-2х+1,6=-2,6
2х=-2,6+2-1,6
2х=-2,2
х=-1,1

Answer 2

$1) 15-(3x-3)=5-4x\\15-3x+3=5-4x\\-3x+4x=5-15-3\\x=-13$

$2)4(x-0.5)-2(x+0.8)=-2.6\\4x-2-2x-1.6=-2.6\\2x=-2.6+2+1.6\\2x=1\\x=0.5$
