Please help me identify the terms and like terms
2 answers:
Step-by-step explanation:
can you send a new picture I can't see the whole problem
The terms are (4.2x), (-3.9), (-5.1x), (6)
like terms are terms that represent the same variable.
-3.9 & 6 both do not represent any varibles, they are just numbers, so they are like terms
4.2x & -5.1x both represent (x) so they are like terms.
to collect like terms, you create a smaller equation, just for them.
so you equations are;
-3.9+6
&
4.2x-5.1x
note: you know to add the 6 as all positive numbers have a + infront, it is just not written.
-3.9+6=2.1
4.2x-5.1x=-1.1x
therefore your equation after collecting like terms is 2.1-1.1x.
Hope this helps :)

Answer:
x=9, y=10. (9, 10). The two numbers are 9 and 10.
Step-by-step explanation:
3x+5y=77
x+y=19
------------------
3x+5y=77
-3(x+y)=-3(19)
---------------------
3x+5y=77
-3x-3y=-57
-------------------
2y=20
y=20/2
y=10
x+10=19
x=19-10
x=9
