-3 (-4 + -x ) = (-4(x) × 2 ) + 6
-3 (-4-x) = (-4x × 2) + 6
-12 + 3x = -8x + 6
3x - 12 = 6 - 8x
add 8x on both sides
11x - 12 = 6
add 12 on both sides
11x = 18
<em><u>x</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>1</u></em><em><u>1</u></em><em><u>/</u></em><em><u>1</u></em><em><u>8</u></em>
Answer:
2 1/2
Step-by-step explanation:
1st, convert the fractions
2 2/3 = 2 4/6 = 16/6
5 1/6 = 31/6
31/6-16/6 = 15/6 = 2 3/6 = 2 1/2
X=1
because you would add two to the other side and have 2x=2 divide by 2 and you would be left with x=1
42-x=58
or, -x=58-42
with change in side sign also chamges we change sides to make like terms in one side and unlike in amother side.
or, -x= 16
or,x=-16.
therefore x=-16...

Answer:
y= 3x + 7 Step-by-step explanation:
y= -1/3x+3 (so, gradient of this line is -1/3).
formula: gradient of line one x gradient of line two= -1 (applies for 2 perpendicular lines only).
So, m1 x -1/3= -1
m1= (
)
m1= 3 (gradient of perp line)
y=mx+c
4= 3 x -1 + c
7=c
therefore, y=3x+7 (eqn of the line perp to y=-1/3x+3)
