x + 5 + 3 = 10
= x + 8 = 10
=> x = 10 - 8
x = 2
x + 1 + 9 = 20
= x + 10 = 20
x = 20 - 10
x = 10
x + 5 + 3 = 10
x + 8 = 10
x = 10 - 8
x = 2
x + 1 + 9 = 20
x + 10 = 20
x = 20 - 10
x = 10
a) x + 5 + 3 = 10
x + 8 = 10
x = 10 - 8 = 2
b) x + 1 + 9 =20
x + 10 = 20
x = 20 - 10 = 10
K mk nha, mk nhanh nhất
\(x+3+5=10\)
\(x=10-3-5\)
\(x=2\)
\(x+1+9=20\)
\(x=20-1-9\)
\(x=10\)
1) x + 5 + 3 = 10
x + 8. = 10
x = 10 — 8
x = 2
2) x + 1 + 9 = 20
x + 10. = 20
x = 20 — 10
x =10
