X+2y=18
-x -x
2y=-x+18
/2 /2 /2
y=mx+b
y=-1/2x+9
the slope is -1/2
Answer:
Its 5
Step-by-step explanation:
Hey there!
Apply fraction cross multiply: if a/b = c/d , then a *d = b*c
2 ( 5x - 2 ) = ( 2x + 4 ) * 4
expand : 2 (5x-2 ) => 2*5x - 2*2 => 10x - 4
expand : ( 2x +4 ) * 4 => 2x * 4 + 4*4 => 8x + 16
10x - 4 = 8x+16
add 4 to both sides:
10x-4+4 = 8x+16+4
simplify :
10x = 8x + 20
subtract 8x from both sides:
10x -8x = 8x+20-8x
simplify:
2x = 20
Therefore:
x = 20 / 2
x = 10
Hope that helps!
Answer:
Step-by-step explanation:
Move 2a to left hand side and change it's sign
Similarly, move 10 to right hand side and change it's sign
