5(4x-5y)-2=453
5(4x-5y)=455
4x-5y=91
When solving for x
4x=5y+91
x= 5y+91/4
When solving for y
-5y=-4x+91
y=-4x+91/-5

Answer:
Hello :
4x² - 8x +3 = 0
4 ( x² - 2x +3/4 ) = 0
4 ( (x² -2x +1) -1 + 3/4) = 0
4 ((x-1)² - 1/4 ) =0
(x-1)² - 1/4 = 0
(x-1)² - ( 1/2 )²=0
( x - 1 -1/2 ) ( x - 1 +1/2 ) = 0
( x - 3/2) ( x - 1/2) = 0
x - 3/2 = 0 or x - 1/2 = 0
two solutions : 3/2 ; 1/2
Answer:
x = 1
Step-by-step explanation:
8x - 5(x - 3) = 18
8x - 5x + 15 = 18 <em>[Expand the brackets]</em>
3x = 3 <em>[Separate variables and constants]</em>
<u>x = 1</u>
