Answer:

-2x² - 8x + 15 = 0

Step-by-step explanation:

Given the following algebraic expression;

x² – 7x + 5

-3x² - x + 10

To add the equation together;

x² – 7x + 5 + (-3x² - x + 10) = 0

x² – 7x + 5 - 3x² - x + 10 = 0

Collecting like terms, we have;

(x² - 3x²) - (7x + x) + (5 + 10) = 0

-2x² - 8x + 15 = 0

-1 + 4x=3x +3<br> Solve for x ?
docker41 [41]

Answer:

x = 4

Step-by-step explanation:

1. Regroup terms.

4x  - 1 = 3x + 3

2. Add 1 to both sides.

4x = 3x + 3 + 1

3. Simplify 3x + 3 + 1 to 3x + 4.

4x = 3x + 4

4. Subtrect 3x from both sides.

4x - 3x = 4

5. Simplify 4x - 3x to x.

x = 4

Therefor, the answer is, x = 4.
