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

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

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