3/4(8x-4)=7x+2 This is a linear equation please help!
aleksandrvk [35]

Simplify the left hand side by multiplying the terms in the parenthesis by 3/4, i.e. divide them by 4 and multiply them by 3:

\dfrac{3}{4}(8x-4)=7x+2 \iff 3(2x-1)=7x+2 \iff 6x-3 = 7x+2

Subtract 6x from both sides:

-3=x+2

Subtract 2 to both sides:

x=-5

Here is your answer

B. (12,30)

REASON:

Given,

y= 2x+6 .......(i)

3x-y= 6 .......(ii)

Putting the value of y from eq.i in eq.ii we get

3x-(2x+6)=6

3x-2x-6=6

=6+6

x=12

Putting x=12 in eq.i we get

y= 2x+6

y= 2×12+6

y= 24+6

y= 30

So,

\bold{x=12 and y= 30}

Hence answer is (12,30) in which x=12 and y=30
