Answer:
x=2.5
Step-by-step explanation:
P=(3x+1)+(x+1)+(3x+1)+(x+1)
24=3x+1+x+1+3x+1+x+1
24=8x+4
24-4=8x
20=8x
x=20/8
x=2.5
P=(3*2.5+1)+(2.5+1)+(3*2.5+1)+(2.5+1)
P=8.5+3.5+8.5+3.5
P=24

Answer:
-77
Step-by-step explanation:
Simply plug in: 
Because the "-" sign is outside the parentheses, you would distribute.
It would then be: -3-4. *positive and negative=negative, negative and negative=positive. -3-4=-7. It would then be: (-7) · ((3-(-4)(2))
(-4)(2)=-8. →(3-(-8))=(3+8)=11. The equation would then be: (-7) · (11)= -77
Answer:
NO
Step-by-step explanation:
We need more than two operations to solve a linear equation . If an equation contains fractions, multiply both sides of the equation by the least common denominator (LCD) to clear fractions.
