How do I solve 4x-2(x-5) = -7+5x+2​

Mathematics
1 answer:
natta225 [31]2 years ago

Answer:

x=5

Step-by-step explanation:

1) Group like terms which will then make the equation 4x-2(x-5)=5x-5

2) Expand the equation (multiply) which will make it 4x-2x+10=5x-5

3) Add similar elements; 2x+10=5x-5

4) Subtract 10 from both sides; 2x=5x-15

5) Subtract 5x from both sides; -3x=-15

6) Divide by 3; x=5

What is the absolute value of 3 above par
lubasha [3.4K]
The absolute value of 3 above par means any value more than the absolute value of 3. The absolute value of 3 is (+) 3 since an absolute value of a number cannot be negative. Above par means positive (+), so more than the specified value of 3. <span />

HELP PLEASEEEE ITS DUE SOON! SHOW YOUR WORK &amp; ILL GIVE BRAINLIEST I PROMISE

Answer:

(2,10) or x=2 y=10

Step-by-step explanation:

<em>1. Pick one of your equations and solve for a variable. I chose the first equation and solved for x.</em>

5x-2y=-10 (Move the -2y to the other side, you need to do the opposite so you add +2y to -10)

5x=2y-10 (Divide the 5 from the x)

x=2/5y-2

<em>2. Now take what you got for x and plug it into the x variable on the other equation.</em>

3(2/5y-2)+6y=66 (Multiply 3 by 2/5y and -2)

6/5y-6=6y=66 (Move the -6 to the other side and add 6/5y to 6y)

36/5y=72 (Since the number on the y is a fraction, you must do the opposite to the other side)

y=72/1 x 5/36 (Flip your fraction and multiply it by the 72)

y=10

<em>3. Now that you have one of the variables solved for, in order to get the other we must plug in what we have to the first equation.</em>

5x-2(10)=-10 (Multiple 2 by 10)

5x-20=-10 (Move -20 to the other side, since you do the opposite add +20 to the -10)

5x=10 ( Divide 10 by 5)

x= 2

<em>4. If needed, plug in the values of x and y to check your solution.</em>

Hope this could help! :)
