Solving equations and formulas

Asked by soblonde6 about 1 month ago, 2 answers.

Okay. I finished the homework [thanks if you answered my q] but could you do step by step with these 4 problems just so I get more of an idea?

1) ex - 2y = 3z [solve for x]

2) y+a OVER 3 = c [solve for c]

3) 3 OVER 5y + a = b [solve for y]

4) v = r...

+ at [solve for a]

1. ex - 2y = 3z
ex = 3z + 2y (move 2y to other side, change sign, you are trying to get the x on one side)
x = 3z+2y / e (divide whole equation by e)

2. uhm 2 is already solved?

Sorry gtg class is over

4. v = r + at
v - r = at
(v-r)/t = a

I cant do 3 right now
