Resolución de Ecuaciones

Transcript

00:00Today we did the 1000 equations exercise, but problem 2, the activity was 5x plus, between

00:10parentheses, minus 7 is equal to x minus, between parentheses, minus 9.

00:16The first thing to do is to get the parentheses, and so that it does not complicate me, we have

00:23to remember to fix the signs, so 9x minus, between parentheses, 9 is like x plus 9, because

00:35for less gives more, and then have to group the terms with x in the first member, the

00:43x to the first member, x passes with 5x, and 7 passes with 9, and we have 5x minus x is equal

00:58to 9 plus 7, then we solve, 5x minus x gives us 4x, and 7 plus 9, 16, and we have 4x is equal

01:14to 16, and to have the final result, we have to divide 4 divided by 16, pass the first

01:22member to the second member, and gives us 4, and the final result is x is equal to 4.
