Question

A) 5x+8=7×-3
B)3. (4×-1)=2. (2×+5)
C)2.(3×-5)=-3 (×+2)

Answer 1

A)
5x + 8 = 7x - 3
8 + 3 = 7x - 5x
11 = 2x
2x = 11
x = 11/2

******************************
B)
3.(4x - 1) = 2.(2x + 5)
12x - 3 = 4x + 10
12x - 4x = 10 + 3
8x = 13
x = 13/8

*********************************
C)
2.(3x - 5) = - 3.(x + 2)
6x - 10 = - 3x - 6
6x + 3x = - 6 + 10
9x = 4
x = 4/9

Answer 2

A) 5x+8=7×-3
5x-7x= -3-8
-2x= -11
x= -11/ -2
x= 11/2

B)3. (4×-1)=2. (2×+5)
12x-3=4x+10
12x-4x=10+3
8x= 13
x= 13/8

C)2.(3×-5)=-3 (×+2)
6x-10= -3x-6
6x+3x= -6+10
9x= 4
x= 4/9
