Answer: x=7
Step-by-step explanation:
8 + 4 = 2(x - 1) combine like terms on the left side
12 = 2(x -1) Distribute on the right side
12 = 2x - 2 Add 2 to both sides
+2 +2
14 = 2x Divide both sides by 2
x= 7
Make all equal or try to even it out depending on what the system is about

↝ x-intercept

↝ y-intercept
y = -5
↝
means that the shade/area is below the graph as shown in the first picture.

↝ x-intercept

↝ y-intercept
y = -3
↝ Since it's "≤" therefore. The shade/area is below the graph. For second picture.
First picture is first inequality
Second picture is second inequality.
