4x - 2(0.5x-1) =14
4x - 1x +2 = 14
3x + 2 = 14
X= 4
Plug that into second equation to get y
In step one, you are supposed to add 25 to both sides, because if you just subtract, it would be -5x-50=53
Answer:
The value of X is 11
X=11
Step-by-step explanation:
Isolate the variable by dividing each side by the factors that don't contain the cariable.
The unkown side legnth is 9 centimeteres long all you had to do was subtract all the numbers from 44 and what your left with is the unknown side.
Step-by-step explanation:
Since sides AD and BC are parallel,
Angle BAD + Angle ADC = 180° (co-interior angles)
Therefore Angle ADC = 180° - 115° = 65°.
