Question

solve for X and verify your result (1)3(2x-1)=5(x-1). (2)3x+4(x-2)=3(x-4)+2​

Answer 1

Answer:

1) 6x-3=5x-5

6x-5x=-5+3

x=-2

putting the value

6 (-2)-3 5 (-2)-5

-12-3 -10-5

-15 = -15

2) 3x+4x-8=3x-12+2

7x-8=3x-10

7x-3x=-10+8

4x=-2

x=-2/4=-1/2

putting the value

7 (-1/2)-8 3 (-1/2)-10

-7/2-8 -3/2-10

(-7-16)/2 (-3-20)/2

-23/2 = -23/2

Answer 2

Step-by-step explanation:

we have,

(1) 3(2x-1) = 5(x-1)

6x-3 = 5x-5

x => -2 ....ans.

for verifying,,

LHS, 3[2(-2)-1] = 3(-5) = -15

RHS, 5(-2-1) = 5(-3) = -15

so, it is true

(2) 3x+4(x-2) = 3(x-4)+2

3x+4x-8 = 3x-12+2

4x = -10+8

x = -2/4

x => -1/2 ....ans.

for verifying,,

LHS, 3(-1/2)+4(-1/2-2)

= -3/2+4×(-5/2)

= -3/2-10

= -23/2

RHS, 3(-1/2-4)+2

= 3(-9/2)+2

= -27/2+2

= -23/2

so, it is true
