b. 7 + 2x = 4x - 3
What is the value of x to make both sides even?

x = 5, It is not possible to make both sides even.

Step-by-step explanation:

Step 1:

7 + 2x = 4x - 3

Step 2:

7 = 2x - 3

Step 3:

10 = 2x

x = 5

Hope This Helps :)

it's not possible

Step-by-step explanation:

we need to make

even

and

also even

but we can't

in the first one

is even no matter what value of x

so to an even you add and odd you get?

odd

so we cannot  make 2x+7 even

nor 4x-3

because

4x=2(2x)

and to an even substract an odd you get?

odd

so you cannot make both sides even

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
