The sum of the given expression { (w - 2.4) + (1 - 0.5w) } is 0.5w - 1.4.
<h3>What is the sum of the given expression?</h3>
Given the expression in the question;
(w - 2.4) + (1 - 0.5w)
Remove the parenthesis
w - 2.4 + 1 - 0.5w
Collect like terms and simplify
w - 2.4 + 1 - 0.5w
w - 0.5w - 2.4 + 1
1w - 0.5w - 2.4 + 1
0.5w - 1.4
Therefore, the sum of the given expression { (w - 2.4) + (1 - 0.5w) } is 0.5w - 1.4.

Solve the following system:
{x + 7 y = 0 | (equation 1)
{2 x - 8 y = 20 | (equation 2)
Swap equation 1 with equation 2:
{2 x - 8 y = 20 | (equation 1)
{x + 7 y = 0 | (equation 2)
Subtract 1/2 × (equation 1) from equation 2:
{2 x - 8 y = 20 | (equation 1)
{0 x+11 y = -10 | (equation 2)
Divide equation 1 by 2:
{x - 4 y = 10 | (equation 1)
{0 x+11 y = -10 | (equation 2)
Divide equation 2 by 11:
{x - 4 y = 10 | (equation 1)
{0 x+y = (-10)/11 | (equation 2)
Add 4 × (equation 2) to equation 1:
{x+0 y = 70/11 | (equation 1)
{0 x+y = -10/11 | (equation 2)
Collect results:
Answer: {x = 70/11
{y = -10/11
