algebra 4x + 15x=16 plz check answer?

Combine like terms:
19x=16

Divide both sides by 19:
x=16/19

4x + 15x = 16
19x = 16
x = 16/19

4x+15x=16
19x=16
x=16/19=.8421
x=.8421

Your answer is wrong.
Check by putting x=3
Left hand side gives, 4*3 + 15*3 = 12+45 = 67
Which is not equal to the Right hand.
hence the answer is wrong!

To find the answer:
4x + 15x=16
19x = 16
x = 16/19

4x+15x=19x
19x=16
x=16/19

X = 16/19

No. if x was 22 then 1 /22x = 1/ 22 not 0. either x = 0 or it is infinity x = 0 if you mean (1/22) x = 0 x is infinity if you mean (1/22x) = 0 since ( 1 / infinity) tends towards 0.

The left says 19x, and the it says that is equal 16; x cannot be 3

Your answer is wrong.

4x + 15x = 16

19x = 16

Divide each side by 19

19x/19 = 16/19

x = 16/19 or 0.821

19 x = 16

x = 16 / 19
