Question

afla valoarea (1000minus h ori2minus 25 ori 4 )impartit la 6 egal cu 143 dau coronita va rog repede

Answer 1

$\frac{1000-h\cdot2-25\cdot4}{6} = 143 \\ 1000-h\cdot2-25\cdot4 = 143\cdot6 \\ 1000-2h-100 = 858 \\ 900-2h = 858 \\ 2h = 900-858 \\ 2h = 42 \\ h= 21$

Answer 2

(1000 - h x 2 - 25 x 4):6 = 143
( 1000 - h x 2 - 100) = 143 x 6
( 1000 - h x 2 - 1oo ) = 858
1000 - 2h - 100 = 858
900 - 2h = 858
900 - 858= 2h
42 = 2h
h = 42 : 2
h = 21
