Question

resolva as questões pra mim passo a passo por favor​

Answer 1

a) 3x +7= x - 3

3x - x +7= -3

2x + 7 = - 3

2x = -3-7

2x=-10

x = -10/2 = -5

b) 4x - 1 = 3x + √2

4x - 3x = √2 + 1

x= √2 + 1

c) 2(x-1) =√7 +x

2x - 2=√7+x

x= √7 +2

d)2(x-1) - 2(x-2) = -(x-3)

2x -2 -2x +4 = -x + 3

2 = -x+3

x= 1
