Thomas given the equation for 2 a + 3 equals negative 3x - 1 + 31 - 11/8 to solve some of the steps in the reasons have already been completed stay a property of numbers for each missing reason

Respuesta :

4(2a + 3) = -3(a - 1) +31 - 11a

firstly, we open the parentheses at the both sides of the equation

4 * 2a + 4*3 = -3 *a - (-3) * 1 +31 -11a

8a + 12 = -3a + 3 + 31 - 11a

we collect the like terms

8a + 3a + 11a +12 = 3 + 31

11a + 11a +12 = 34

22a + 12 = 34

the next step is to isolate 22a then we have

22a = 34 -12

22a = 22

divide both sides by 22

22a/22 = 22/22

a = 1
