What is the value of x in the question 7x+2y=48,when y =3
2 answers:
You want to find the value of x, and you know that y = 3.
1) First plug y = 3 into the equation:
<span>7x + 2y = 48
7x + 2(3) = 48
7x + 6 = 48
2) Now solve the equation </span>7x + 6 = 48 for x by subtracting 6 from both sides, then dividing both sides by 7.
7x + 6 = 48
7x = 42
x = 6
--------
Answer: x = 6
