To solve the equation you need to isolate x onto one side of the equation.
I assume the equation is ( x / 2 ) + 1 = ( -5 )
First you subtract 1 from each side ( x / 2 ) + (1 - 1) = ( -5 ) - 1:
( x / 2 ) = -6
Next we have x over 2 so you multiply each side by 2 to isolate the x:
( 2x / 2 ) = -6 * 2
Which simplifies to x = -12
The solution to the equation is x = -12

Answer:
SAS Similarity Theorem
Step-by-step explanation:
we know that
<u>SAS Similarity Theorem</u>: States that if two sides in one triangle are proportional to two sides in another triangle and the included angle in both are congruent, then the two triangles are similar
In this problem
∠HJZ=∠RJW ----> by vertical angles
and
WJ/HJ=JR/JZ
substitute the values
8/4=6/3
2=2 ----> is true
so
Two sides of triangle HJZ are proportional with the two corresponding sides of triangle WJR and the included angle is congruent
therefore
Triangles are similar by SAS Similarity Theorem
The coefficient by "x" (the slope) in slope-intercept form of linear equation (y=mx+b) indicate how fast the graph is going up (if slope is positive) or down (if slope is negative). The bigger absolute value of the number - the steeper the graph
