Question

0,11x+0,08x=45.6 2.9x-1.1x=5.04 x-0.64x=2.808 7x+9x+0.32=2.72 5y+7y-0.024=0.204

Answer 1

0,11x+0,08x=45.6
0,19x=45,6
x=45,6:0,19
x=240

2.9x-1.1x=5.04
1,8x=5,04
x=5,04:1,8
x=2,8

x-0.64x=2.808
0,36x=2,808
x=2,808:0,36
x=7,8

7x+9x+0.32=2.72
16x+0,32=2,72
16x=2,72-0,32
16x=2,4
x=2,4:16
x=0,15

5y+7y-0.024=0.204
12y-0,024=0,204
12y=0,204+0,024
12y=0,228
y=0,228:12
y=0,019
