How do you solve # 7a - 3 = 3 - 2a #?

Answer 1

Savannah Anderson

#color(green)(a=2/3)#

Given #color(white)("XXX")7a-3=3-2a#

Add #2a# to both sides: #color(white)("XXX")9a-3=3#

Add 3 to both sides #color(white)("XXX")9a=6#

Divide both sides by #9# #color(white)("XXX")a=2/3#

To solve 7a - 3 = 3 - 2a, you first add 2a to both sides of the equation to isolate the terms containing a on one side. Then, you add 3 to both sides to further isolate the term containing a. Next, you combine like terms and solve for a. The solution is a = 1.
