Question

Just onve more question
same as the other one

Answer 1

multiply out the brackets 4(5-2x)
4*5=20
4*2x=8x
put this into the equation
20-8x+3=7
- which can also be written as 23-8x=7
by minusing 7 from both sides you get:
16-8x=0
minus 16 from both sides
-8x=-16
from this we can see that x=2

Answer 2

Answer:

x = 2

Step-by-step explanation:

4(5 - 2x) + 3 = 7

Distributive property ,    multiply (5-2x) by 4:

20 -8 x + 3 = 7

Combine like terms:

23 - 8x = 7

Inverse add and subtract:

23 - 7 - 8x + 8x = 7 - 7 + 8x

16 = 8x

Inverse divide:

16/8 = 8x/8

x = 2
