Answer:

#x = 4#

Explanation:

#5 = -3 + 2x#

We want to solve for #x#, so we need to make #x# alone. To do that, first add #color(blue)3# to both sides of the equation:
#5 quadcolor(blue)(+quad3) = -3 + 2x quadcolor(blue)(+quad3)#

#8 = 2x#

Now divide both sides by #color(blue)2#:
#8/color(blue)2 = (2x)/color(blue)2#
#4 = x#

So the final answer is
#x = 4#

Hope this helps!

Answer:

#x = 4#

Explanation:

We are given #5 = -3 +2x#

Add +3 to both sides.

#5 + 3 = -3 + 3 + 2x#

Swap sides and sum.

#- 3 + 3 + 2x = 5 + 3#
#" " 0 + 2x = 8#

Divide both sides by 2.

#(2x)/2 = 8/2#

And simplify.

#x = 4#
