Answer:
1
Step-by-step explanation:
-2(x-4)+1=7
First Distribute the -2.
-2x+8+1=7
Subtract the 8 and 1 from the whole equation.
-2x=-2
Divide both sides of the equation by -2.
x=1
I hope this helps!
Answer:
The number is -1
Step-by-step explanation:
Which TWO expressions are equivalent to<em> </em><em>(x - y) </em>2/3 - 3/4 <em>(y-x)</em>
Okay so here you go
<span>Decimal Form: -1.266667
</span>
Fraction form: -19/15
hears how:
Simplify brackets
-2/3 - 3/5
Simplify: -19/15
First, find the slope of the line thru these 2 pts:
5-4
m = --------- = -1/2
2 -4
Use the slope-intercept formula y = mx + b:
5 = (-1/2)(2) + b. Then the y-intercept is 5 + 1, or 6: y = (-1/2)x + 6
Multiplying this entire result (3 terms) by 2 results in 2y = -x + 12, or
x + 2y = 12 (answer)
