How would I solve these equations?

Question

This is what my worksheet says:

If you were to solve the following, what would your first step be?

9) 2x-7=3
a. subtract 7
b. multiply by 2
c. divide by 2
d. add 7

10.) -4=8+(x over 4)
a. subtract 8
b. add 8
c. multiply by 4
d. add 4

11.) 2-4x= -6
a. add 2
b. subtract 2
c. divide by -4
d. add 6

12.) -5+(3 over 4 x)=1
a. multiply by (4 over 3)
b. subtract 5
c. subtract 1
d. add 5

i dont get these AT ALL. what are the answers? they dont make any sense.

Answer 1

AT All times The LEFT HAND SIDE {LHS} Must Equal RIGHT HAND SIDE {RHS}

Your questions are asking what is the FIRST Step in solving the equations
So
in 9) you would add 7 to both sides {The net effect is 2x = 3 + 7}

10) your next step would be to Multiply by 4 { nett effect is -16 = x}

And so on ...

Answer 2

9) 2x-7=3
d. add 7

10.) -4=8+(x over 4)
c. multiply by 4


11.) 2-4x= -6
b. subtract 2

12.) -5+(3 over 4 x)=1
d. add 5

Answer 3

I'm doing your homework but #9 a #10 c #11 c #12 a. I hope this helped and good luck on your homework!!

Answer 4

2x-7=3

add 7
2x-7+7=3+7
2x=10
x=5

-4=8+ x/4
multiply by4
-16=32+x
--48=x

2-4x=-6
-2+2-4x=-6-2
-4x=-8
-4x/-4=-8/-4
x=2

-5 +(3/4x)=1
add 5
-5+5+3/4x=1+5
3/4x=6
3/4(4/3)x=6(4/3)
x=8
