Question

Solve the following equations

1. -5=x+3
2. x-3=-5
3. 6.4=4x
4. -9= r/4
5. -9= 5/17n

Answer 1

1. -5 =x+3
x = -5 - 3
x = -8

2. x-3=-5
x = -5 +3
x = -2

3. 6.4 = 4x
x = 6.4 / 4
x = 1.6

4. -9= r/4
r = (-9)*4
r = -36

5. -9= 5/17n
n = (-9) (17/5)
n = -30.6

Answer 2

1.x=-8
2.x=-2
3.x=1.6
4.r=-36
5.n=- 153/5
