If y=4x and x=25 , find the value of y

Answer 1

Hey there! So, what we know is that y is equal to four times the value of x, and x is equal to 25. This means that we can substitute 25 in for x because we know that 25 is the value of x. The equation now looks like y=4(25). 4 multiplied by 25 is 100, so the value of y=100. Hope this helps!
