0.26x + 0.09x = 8- 0.45x => 0.35x + 0.45x = 8 => 0.80 x = 8 => x = 8/0.8 = 10 Now put this value of x in the given equ if both LHS and RHS comes equal your answer is correct

Given equation is
0.26x+0.09x=8-0.45x
Combine like terms
0.35x=8-0.45x
Adding 0.45x on both sides
0.35x+0.45x=8
0.8x=8
Dividing both sides by 0.8
x=8/0.8
x=10
check
substituing x=10 in 0.26x+0.09x=8-0.45x
0.26(10)+0.09(10)=8-0.45(10)
2.6+0.9=8-4.5
3.5=3.5
