Question

do as directed 2. solve the following (a) 4x -2 = 10 (b) 6x -7 = 5 + 2x (c) x+1/2x+3 = 3/8​

Answer 1

Step-by-step explanation:

a) 4x =10+2

4x= 12

x = 12/ 4

x= 3

b) 6x = 5+7

x= 12/6

x= 2

c) x +1/2x= 3/8 - 3/1

1/2xcube = 3/8- 3×8/8

1/2xcube = 24- 3/ 8

1/2xcube = 21/ 8

xcube = 21/8- 1/2

xcuube = 21- 4/ 8

xcube = 17/8

now cube root of 17/8

then you get the answer

Answer 2

Answer:

a) x = 3    b) x = 2    c) x = 1/2

Step-by-step explanation:

a) 4x - 2 = 10

= 4x = 10 + 2

= x = 12/4 = 3

b)6x - 7 = 5

= 6x = 5 + 7

= x = 12/6 = 2

c)x+1/2x+3 = 3/8

= 8( x + 1 ) = 3( 2x + 3 ) [ by cross multiplying ]

= 8x + 8 = 6x + 9

= 2x = 1

x = 1/2
