Answer:

Step 1: Make x the subject by moving all x terms to one side;

a)  4x-2x=7+3

Step 2; solve the linear equation

2x=10

x=10/2

x = 5

b) 2x-7x = -14-6

-5x = -20

x = -20/-5

x= 4

Hope this helps :) ! I'd apreciate if you'd mark my answer brainliest because ive been on the same rank for quite a loong time :(

A) 4x-3=2x+7

Let's say x is 5

4x5-3 = 2x5+7

20-3 = 10+7

17=17

So x is 5

B) 2x+6 =7x -14

Let's say x is 4

2x4+6 = 7x4-14

8+6= 28-14

14=14

So x is 4

Answer:

-14x+4

Step-by-step explanation:

So the first set of paranthese don't really matter so you can rewrite it to this

-7+6-(-2x+9x-2)

Then  infront of the ( there is a - which means a -1. Now just do the disbutive property.

-7x+6+2x-9x+2

Now add like terms and you get your finial answer!

If KX - 8Y + 4 =0 is parallel to the line who’s equation is 3X -4Y+8 = 0. What is the value of K
Alex_Xolod [135]

So - first you gotta put it in the y = mx + b form.


4Y = 3X +8

=> y = 4/3X + 1/2

A parallel line has the same slope. So if 3X - 4Y + 8=0 has a slope of 4/3 then the value of K must also be 4/3
