Step-by-step explanation: <em>* x is the shortened of saying 1x *</em>
Add like terms (out of the equation combine +3x and +1x which is<u><em> 4x</em></u>. And combine +2and -6 which is <u><em> -4 </em></u>) and now the equation is reads 4x -4= 25
Move the "-4" to the other side pf the equation by Addition Property of Equality 4x -4 = 25 . +4 +4 . 4x = 29
Then, separate the 4 from the x to get it by itself by Dividing 4 into 4x . *Remember what you do to one side of the equation do to other side* 4x/4 = 29/4
The answer now depends what the teacher wants if she want it to stay as an improper fraction it will be 29/4 if it wanted in Mixed number its 7 and 1/4 and if its necessary to have in decimal form its 7.25.
x + 3 = 3(y + 2)/2 [Multiplied both sides by 3] so x + 3 = (3y + 6)/2 2(x + 3) = 3y + 6 [Multiplied both sides by 2] 2x + 6 = 3y + 6 2x = 3y [Subtracted 6 from both sides] x = 3y/2 [Divided both sides by 2] x/3 = y/2 [Divided both sides by 3]
