Which equation has no solution?
Lostsunrise [7]

Answer:

Step-by-step explanation:

4(x+3)+2x = 6(x+2)  →   4x +12 +2x = 6x + 12 → No solution

5 + 2(3+2x) = x + 3(x+1)  →  5 + 6 + 4x = x + 3x + 3 → No solution

5(x + 3) + x = 4(x+3) + 3 → 5x + 15 + x = 4x +12 +3 → 6x + 15 = 4x + 15 → x= 0

4 + 6(2+x) = 2(3x +8)  →   4 + 12 + 6x = 6x + 16  → No solution

Find the value of x<br> Please help out!!
Vanyuwa [196]

Answer:

x = 12

Step-by-step explanation:

(2x + 4) and (12x + 8) are same- side interior angles and sum to 180° , then

2x + 4 + 12x + 8 = 180

14x + 12 = 180 ( subtract 12 from both sides )

14x = 168 ( divide both sides by 14 )

x = 12
