Hiya. I'm going to rewrite the second equation.
By subtracting 5x by both sides, I'll be able to have y by itself:
-y=-5x+13
I'm going to then divide both sides by -1 to get:
y=5x-13.
Then, I'm going to plug that equation into the first equation
3x+2(5x-13)=39
Factor:
3x+10x-26=39
Combine like terms:
13x=65
Divide both sides by 13 to get x by itself to get x=5
Plug this back into the equation of y=5x-13
y=5(5)-13 to get y=12
Answer:
x=3
Step-by-step explanation:
first let's try to get just 3x on one side. to do this we can subtract 2 from both side of the equation.
3x+(2-2)=11-2
3x=9
now we have to isolate the variable we can divide both sides by 3:
3x/3=9/3
x=3
and you get the answer that x is 3
False because doing the math doesn’t match
