Answer 2

Let's solve each of these equations step by step:

1. 2x + x - 10 = 59

First, combine like terms on the left side:

3x - 10 = 59

Now, add 10 to both sides to isolate the variable:

3x = 59 + 10 3x = 69

Finally, divide both sides by 3 to solve for x:

x = 69 / 3 x = 23

So, the solution for the first equation is x = 23.

2. 14 - 2y + 76 = 100

Combine like terms on the left side:

14 + 76 - 2y = 100

90 - 2y = 100

Now, subtract 90 from both sides:

-2y = 100 - 90 -2y = 10

Divide both sides by -2 to solve for y:

y = 10 / (-2) y = -5

So, the solution for the second equation is y = -5.

3. (7q - 2a) × 8 = 80

First, divide both sides by 8:

7q - 2a = 80 / 8 7q - 2a = 10

Now, add 2a to both sides to isolate the term with 'q':

7q = 10 + 2a

Finally, divide both sides by 7 to solve for q:

q = (10 + 2a) / 7

So, the solution for the third equation is q = (10 + 2a) / 7.
