Question

let 3 x + 4 = 7 x + 2 y then x is​

Answer 1

3x+4=7x+2

Subtract 7x from both sides.

3x+4−7x=2

Combine 3x and −7x to get −4x.

−4x+4=2

Subtract 4 from both sides.

−4x=2−4

Subtract 4 from 2 to get −2.

−4x=−2

Divide both sides by −4.

x= −4/-2

​  

Reduce the fraction  

−4/−2

​=0.5 to lowest terms by extracting and canceling out −2.

x=  2/1

I hope this answer helps you

Answer 2

Answer:

x =1-y/ 2

I hope u got it

Step-by-step explanation:

3x+4=7x+2y

then, 4-2y= 7x-3x

then, 4-2y= 4x

then x = 4-2y/4

then, x= 1-y/2
