How do you solve #5( x + 1) = 7 2( 5x + 8)#?
By the usual algebraic manipulations, we get
First let's distribute the constant factors:
Now we subtract:
Now we move all the x terms to one side and the constant terms to the other. Terms negate when they move to the other side because what we're really doing is adding the negative to both sides:
Now we add and subtract:
Now we divide both sides by 15 for our solution:

To solve the equation 5(x + 1) = 7  2(5x + 8), follow these steps:

Distribute the terms inside the parentheses: 5x + 5 = 7  10x  16

Combine like terms on both sides of the equation: 5x + 5 = 10x  9

Add 10x to both sides to move all x terms to one side: 5x + 10x + 5 = 9

Combine like terms again: 15x + 5 = 9

Subtract 5 from both sides: 15x = 14

Divide both sides by 15 to isolate x: x = 14/15
So, the solution to the equation is x = 14/15.
