Question

Помогите решить уравнения

5(2+1.5)-0.5х=24

4х+3(2х-1.5)-5=5.5

-5(х+1)+4х=3

Answer 1

5(2+1,5)-0,5x=24
10+7,5-0,5x=24
17,5-0,5x=24
-0,5x=24-17,5
-0,5x=6,5
X=6,5:(-0,5)
X=-13

4x+3(2x-1,5)-5=5,5
4x+6x-4,5-5=5,5
10x=5,5+4,5+5
10x=15
X=1,5

Answer 2

5(2+1.5)-0.5х=24
10+7.5-0.5х=24
-0.5х=24-10-7.5
-0.5х=6.5
х=6.5/0.5
х=13

4х+3(2х-1.5)-5=5.5
4х=6х-4.5-5=5.5
4х-6х=-4.5-5-5.5
-2х=-6
х=-6\(-2)
х=3

-5(х+1)+4х=3
-5х+-5+4х=3
-5х+4х=3+5
1х=8
х=8/1
х=8
