Question

7(x+3)+8(x+4)=15(x+6)

Answer 1

$7(x+3)+8(x+4)=15(x+6) \\7x+21+8x+32=15x+90\\7x+8x-15x=90-21-32\\0=37$

Answer 2

To solve the equation 7(x+3) + 8(x+4) = 15(x+6), you'll want to simplify and isolate the variable, typically x. Here are the steps to solve it:

1. Distribute the constants on the left side and right side of the equation:

7(x+3) + 8(x+4) = 15(x+6)

Expand each term:

7x + 21 + 8x + 32 = 15x + 90

2. Now, combine like terms on both sides of the equation:

(7x + 8x) + (21 + 32) = 15x + 90

15x + 53 = 15x + 90

3. At this point, you can see that there is a 15x term on both sides of the equation. To isolate x, you'll want to get rid of one of those 15x terms. You can do this by subtracting 15x from both sides of the equation:

(15x + 53) - 15x = (15x + 90) - 15x

53 = 90

4. Now, you can see that the equation 53 = 90 is not true. In fact, there is no solution to this equation because the variable x canceled out during the simplification process. This means that there is no value of x that will make the original equation 7(x+3) + 8(x+4) = 15(x+6) true.

Therefore, the solution to the equation is "No Solution."
