solve: m/5 + 8 =7. y - 7 =-4. h + (9) =-4. x/-4 =9. -2p + 5 =1?

Answer 1

m/5+8=7
m/5=-1
m/5(5)=-1(5)
m=-5

y-7=-4
y=3

h+9=-4
h=-13

x/-4=9
-4(x/-4)=9(-4)
x=-36

-2p+5=1
-2p+5-5=1-5
-2p=-4
-2p/-2--4/-2
p=2

Answer 2

m/5 + 8 =7, M = -5
y - 7 =-4, y = 3
h + (9) =-4, h = -13
x/-4 =9, x = -36
-2p + 5 =1, p = 2

Answer 3

the trick to these is to get the letter by itself by doing the opposite to what's being done to it to both sides of the equation. (both sides of the equals sign)
so for the first one you're adding 8 to the bit with the letter so we take away 8 from both sides. this gives m/5 + 8 -8 =7 -8
8-8=0 so we have m/5 +0 = m/5 = 7-8 =-1 or m/5=-1
now the m is getting divided by 5 so we have to times by 5 to undo it.so m/5 x 5 = -1 x 5 or m = -5. i'll do 1 more for you then let you try the others.
in the last equation we're adding 5 so we take 5 away from both sides ( of the equals sign). this gives -2p+5-5=1-5
so -2p = -4. now we divide by -2 this gives p = -4/-2 the minus signs cancel so it becomes 4/2 which is 2.
quick question for you alex, do you ever do your own maths homework?!

Answer 4

Let me give you some rules to follow to help you do your problems. 1. If you have a number added or subtracted to a variable, do the opposite function to both sides to get the variable standing alone. Example: 1] y + [-3] = 7 Step 1: Subtract -3 from both sides and simplify. y + [-3] - [-3] = 7 - [-3] y - 3 + 3 = 7 + 3 y = 10 2. If you have a variable multiplied or divided by a number, do the opposite function to both sides to get the variable standing alone: Example: 4] -6x = 24 Step 1: Divide both sides by -6 and simplify. -6x/-6 = 24/-6 x = -4 On #14, you need to use the Distributive Property and make the 2[x + 3] into 2x + 6. Hope that helps ;)
