There are 58 students in the first class of grade 6. The sum of 1 / 4 girls and 2 / 5 boys is 19. How many boys and girls are there in the first class of grade 6? Do it by solving the equation,

There are x girls and 58-x boys
1/4X+2/5(58-X)=19
1/4X+116/5-2/5X =19
(-3/20)X=(-21/5)
X=28
A: there are 30 boys and 28 girls in class 1 of grade 6
