2x+7=12x-6 looking for x
Rzqust [24]
Hey!

Let's start by writing the problem:
2x+7=12x-6
Subtract 7 from both sides.
2x+7-7=12x-6-7
2x=12x-13
Subtact 12x from both sides.
2x-12x=12x-13-12x
-10x=-13
Divide both sides by -10.
\frac{-10x}{-10}=\frac{-13}{-10}
x=\frac{13}{10}

Let me know if you have any questions regarding this problem!
Thanks!

y = mx + c ( m is the slope and c the y- intercept )

y = 5x + 3 ← is in slope- intercept form

with slope m = 5

Parallel lines have equal slopes , then

NEED AN ANSWER ASAP How are the terms in parentheses affected when multiplied by a negative coefficient when the distributive pr
Anna [14]

The Distributive Property is an algebra property which is used to multiply a single term and two or more terms inside a set of parentheses.

The Distributive Property tells us that we can remove the parentheses if the term that the polynomial is being multiplied by is distributed to, or multiplied with each term inside the parentheses.

If a number outside the parentheses has a negative sign then the first and simplest way is to change each positive or negative sign of the terms that were inside the parentheses. Negative or minus signs become positive or plus signs. Similarly, positive or plus signs become negative or minus signs.
