Question

5( х - 1) - 4( х - 2 ) = 10

Answer 1

Ответ:

$5(x - 1) - 4(x - 2) = 10 \\ 5x - 5 - 4x + 8 = 10 \\ 5x - 4x = 10 + 5 - 8 \\ 1x = 15 - 8 \\ x = 7$

Answer 2

$5(x - 1) - 4(x - 2) = 10 \\ 5x - 5 - 4x + 8 = 10 \\ x + 3 = 10 \\ x = 10 - 3 \\ x = 7$

Answer 3

Let's solve the equation $5(x - 1) - 4(x - 2) = 10$ for $x$:

Distribute the terms on both sides of the equation:

$5x - 5 - 4x + 8 = 10.$

Combine like terms:

$x + 3 = 10.$

Subtract 3 from both sides:

$x = 7.$

So, the solution to the equation is $x = 7$.
