Question

A)7(×-2)=5(×+3)
B)2(×-5)+4(×-1)=0
C)3(2×-1)=-2(×+3)
Com conta,por favor!!!

Answer 1

a) 7X - 14 = 5X 15
7X - 5X = 15 + 14
2X = 29
X = 29
2
X = 14,5

b) 2X -10 = 4X - 4 = 0
4X - 2X -4 + 10 = 0
2X + 6 = 0
X = 6
2
X= 3

c) 6X - 3 = - 2X + 6
6X + 2X = 6 + 3
8X = 9
X = 9
8
X = 1,125

Espero ter ajudado...... ♡

Answer 2

a) 7x - 14 = 5x + 15
7x - 5x = 15 + 14
2x = 29
x = 29/2
x = 14,5

b) 2x - 10 + 4x - 4 = 0
2x + 4x = 4 + 10
6x = 14
x = 14/6
x = 7/3 ou 2,33...

c) 6x - 3 = - 2x - 6
6x + 2x = -6 + 3
8x = -3
x = - 3/8
x = - 0,375
