6/5 because you add 1.5 to both sides, the. Add 2 to both sides, then divide to get a by itself
The answer is (x+1)-(2x-4)=6

Answer:
x = -1
Step-by-step explanation:
A graphical solution can avoid extraneous solutions. The attachment shows the one solution is x = -1.
__
Squaring both sides gives ...
x +5 = (x +3)² = x² +6x +9
Putting this in standard form, we have ...
x² +5x +4 = 0
(x +1)(x +4) = 0 . . . . . factor
x = -1 or -4 . . . . . . . . values of x that make the factors zero
__
Since we require the root to be non-negative, we must have ...
x +3 ≥ 0
x ≥ -3
The only solution that satisfies this requirement is x = -1. The solution x = -4 is extraneous. The solution is x = -1.
Answer:
8x-2
Step-by-step explanation:
Product of a number and 8 is 8x because you are substituting x for the number.Then you will subtract 2
Step-by-step explanation:
m <em>L</em><em> </em>1 = 180°-75° = 105° ( angles in one side)
m <em>L</em><em> </em>2 = 75° (corresponding angles)
