(2^3)=2*2*2=8
(2^-7)=1/2*1/2*1/2*1/2*1/2*1/2*1/2=1/128
8*1/128=1/16=.0625

Solve the equation 3/4x+3-2x = -1/4+1/2x+5
elena55 [62]
Hi there! The answer is x = -1

Let's solve this equation step by step!
\frac{3}{4} x + 3 - 2x = - \frac{1}{4} + \frac{1}{2} x + 5

First collect terms.
- 1 \frac{1}{4} x + 3 = \frac{1}{2} x + 4 \frac{3}{4}

Subtract (1/2)x from both sides.
- 1\frac{3}{4} x + 3 = 4 \frac{3}{4}

Subtract 3 from both sides.
- 1\frac{3}{4} x = 1 \frac{3}{4}

And finally divide by -1 3/4
x = \frac{7}{4} \div - \frac{7}{4} = \frac{7}{4} \times - \frac{4}{7} = - \frac{28}{28} = - 1

Solve this system by substitution, y = 3 y=-3x + 6 *Remember to write your answer as a coordinate point (x, y). I​
storchak [24]
Take y=3 and plug it into y=-3x+6. This gives you 3=-3x+6. Solve for x, you get x=1. Now plug 1 into y=-3x+6 and you get 3. Answer is (1,3)

5(2x+6)=-4(-5-2x)+3x step by step
Oksi-84 [34.3K]

Answer:

x = 10

Step-by-step explanation:

Okay, let's solve :)

So first we have to distribute on the left side(it doesn't matter which side FYI)

When we do, we have :

10x + 30 = -4(-5-2x)

Now we distribute on the right side! Remember, negative * negative = positive.

10x + 30 = 20 + 8x + 3x

Let's simplify on the right side to

10x + 30 = 20 + 11x

Now, let's subtract 10x on both sides to get

x + 20 = 30(i simply flipped the equation)

Subtract 20 on both sides to get!

x = 10!
