Answer:

#a= -5#

Explanation:

Original Equation: #5a + 3 -3a = -7#

#5a# and #-3a# are like terms, so you can combine them

#2a+3=-7#

Now, you only have one term with a variable, and just solve for #a# by subtracting both sides by #3# then dividing by the coefficient of #a#

#2a=-10#

So,

#a=-5#
