Question

What is the value of x in the equation 7x + 2y = 48 , when y = 3?

Answer 1

Substitute the value of y = 3 into the expression,
7x + 2y = 48
7x + 2(3) = 48
7x = 48 - 6
7x = 42
x = 42/7
x = 6

So, your final answer is 6

Hope this helps!

Answer 2

7x+2(3)=48
Soo its 7x+6=48
U put the 6 to the other side it becomes subtraction.
=7x=48-6=7x=42
To find x=42/7
Soo x=6
