Resolver las siguientes ecuaciones A) x + 4 = 15 B) 1 + x - 8 = 12 C) 2×y = 6 D) j%3 = 7.
Resolver las siguientes ecuaciones A) x + 4 = 15 B) 1 + x - 8 = 12 C) 2×y = 6 D) j%3 = 7.
ax² + bx + c = 0
En resumen
A)x + 4 = 15 x = 15 - 4 x = 11 b)1 + x - 8 = 12 x - 8 = 12 - 1 x - 8 = 11 x = 11 + 8 x = 19 c) 2(y) = 6 y = 6 / 2 y = 3 d)j / 3 = 7 j = 7×3 j = 21.
A)x + 4 = 15
x = 15 - 4
x = 11
b)1 + x - 8 = 12
x - 8 = 12 - 1
x - 8 = 11
x = 11 + 8
x = 19
c) 2(y) = 6
y = 6 / 2
y = 3
d)j / 3 = 7
j = 7×3
j = 21.
