Reduce la siguiente expresión algebraica: -3x +4 -x +1= 3a -3b +a +b=
-6 +3a -5b +1 +2a -b=
-6 +3a -5b +1 +2a -b=
3a -b -7a -3 -b +1=

Necesito que me reduzcan las expresiones algebraicas

-3x +4 -x +1 =  5 - 4x

3a -3b +a +b =  4a - 2b

-6 +3a -5b +1 +2a -b =  5a -6b -5

3a -b -7a -3 -b +1= -2b -4a -2

Hope this helps ^-^

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
