4x = 76
Where x is how many awnsers he got correct and 4 how many points each correct question awnsered.
Now you just have to isolate x by dividing both sides of the equation by 4
4x/4 = 76/4
x = 19
So he got 19 questions right and 10 awnsers wrong. In total there were 29 questions on his test

Distance/Speed = Time
Distance=1,071 Speed=63 Time=x
1,071/63 = x
17 = x
Answer:
The value of x = 2.
The value of y = 1.
Step-by-step explanation:
The length of opposite sides of a parallelogram are equal.
Hence, the length of 4x - 3 and x + 3 are equal.
Similarly, the lengths of 3y and 5y - 2 are equal.
And
Therefore, the values of x and y are: 2; 1 respectively.
