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

Can someone help me.​
salantis [7]

Answer:

see explanation

Step-by-step explanation:

substitute the values of x in the table into g(x)

Using the rule of exponents

a^{-m} = \frac{1}{a^{m} }

g(- 2) = 4^{-2} = \frac{1}{4^{2} } = \frac{1}{16}

g(- 1) = 4^{-1} = \frac{1}{4}

g(0) = 4^{0} = 1

g(1) = 4^{1} = 4

g(2) = 4² = 16

Is 2 and 4.5 equivalent ​
o-na [289]

2 and 4.5 is not equivilant since 2 and 4.5 cannot go together (the 0.5 does not help and so it does not make it equivalent.)

Hope this helped!
