What is the value of 2x + 6y when x = 7.1 and y = 8.4

64.6

You can solve this by multiplying 7.1 by 2 (14.2) and then multiplying 8.4 by 6 (50.4) then adding the totals. (50.4+14.2 is equal to 64.6)

Hope this helped!

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3
