Question

Find the value of x and Check the answer also:
0.4(3x –1) = 0.5x + 1
8x – 7 – 3x = 6x – 2x – 3
10x – 5 – 7x = 5x + 15 – 8
4t – 3 – (3t +1) = 5t – 4
5(x – 1) – 2(x + 8) = 0
0.25 (4x – 5) = 0.75x + 8

Answer 1

Answer:

Step-by-step explanation:

1. 0.4(3x - 1) = 0.5x +1

= 1.2x -0.4 = 0.5+1

=1.2x - 0.5x = 1+0.4

=0.7x =1.4

x = 1.4/0.7 = 2

2. 8x -7-3x = 6x -2x -3

=5x-7 = 4x-3

=5x -4x = -3+7

x = 4

3. 10x -5-7x =5x+15-8

= 3x-5=5x+7

=3x-5x= 7+5

= -2x=12

x = -12/2 = -6

Answer 2

Step-by-step explanation:

2x-8=78

$2x - 8 = 78$
