Answer:
x = -14
Step-by-step explanation:
Simplifying
7x + 156 = 9x + 184
Reorder the terms:
156 + 7x = 9x + 184
Reorder the terms:
156 + 7x = 184 + 9x
Solving
156 + 7x = 184 + 9x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-9x' to each side of the equation.
156 + 7x + -9x = 184 + 9x + -9x
Combine like terms: 7x + -9x = -2x
156 + -2x = 184 + 9x + -9x
Combine like terms: 9x + -9x = 0
156 + -2x = 184 + 0
156 + -2x = 184
Add '-156' to each side of the equation.
156 + -156 + -2x = 184 + -156
Combine like terms: 156 + -156 = 0
0 + -2x = 184 + -156
-2x = 184 + -156
Combine like terms: 184 + -156 = 28
-2x = 28
Divide each side by '-2'.
x = -14

Expression for area of triangle
This is calculated using
Assume that:
The equation becomes
Because the ones place is under 5, we round down, and 392 becomes 390 when rounded to the nearest 10
If we solve the left side of the given equation,
1/a + 1/b = 1/c
we get an answer of,
b+a / ab = 1/c
Since ab = c, we can conclude that b + a is 1. The average of these two numbers is equal to there sum divided by 2. The answer is therefore equal to 0.5.
<h3>−2x + 14 = 12</h3>
<em>Subtract</em><em> 14 </em><em>from both sides.</em>
<h3>−2x = 12 − 14</h3>
<em>Subtract </em><em>14</em><em> from </em><em>12 </em><em>to get </em><em>−2.</em>
<h3>−2x = −2</h3>
<em>Divide both sides by</em><em> −2.</em>
<h3>x= -2/-2</h3>
<em>Divide </em><em>−2</em><em> by </em><em>−2</em><em> to get 1.</em>
<h3>x = 1</h3>
