Y=10-4x/-4 => 3x=5-2(10-4x/-4)
3x=5+5-2x
5x=10
x=2 => 6+2y=5
2y=-1
y= -1/2
y=-0.5
Answer:
l = 6
+ 2a - 1
Step-by-step explanation:
the area (A) of a rectangle is calculated as
A = lw ( l is the length and w the width )
given A = 18
+ 6a² - 3a and w = 3a , then
3aw = 18
+ 6a² - 3a ( divide each term by 3a )
w =
+
-
= 6
+ 2a - 1
1 5/8
