6 times x (the variable) plus 14 so basically 6x+14
B. Y= x+ 48 trust me bro.
<span>17 protons and 20 neutrons add up to a molecular mass of 37</span>
Answer:
2x + 1, 3x + 9
Step-by-step explanation:
should be the answer
2x+y=20 and -5y=6x+12 are your equations.
You can turn 2x+y=20 into y=-2x+20
Substitute this value of y into the other equation.
-5(-2x+20)=-6x+12
10x-100=-6x+12
16x=112
x=7
Substitute this value of x into the other equation.
2(7)+y=20
y=6
Your answer is x=7 and y=6.
