Equivalent equations help you to knock out the <span> choices and solve the problems more easier.
for example
</span>x + 6y = 8
<span>2x + 4y = 8
</span>multiply first equation to get rid of from x
2x+12y=16
2x+4y=8
now subtract second equation from first
8y=8
y=1
now put value of y in seond equation
2x+4(1)=8
2x=8-4
2x=4
x=2
hence,
<span>equivalent equations help you to solve a system of equations</span>

Answer:
A. True
B. False
C.True
D. True
E. Sometimes true
F. False
G. True
H. Sometimes true.
Explanation:
If I got it wrong, I will try better next time.
Step-by-step explanation:
x/4+3y^2
=8÷4 + 3×3^2
=2+9^2
=2+81
=83
