Question

Find the value of the variables
a) X + 7 = 10x - 7
b) 4x + 5y = 10x - (-5y)
c)33x + 14 = 3
d)x + 10x-43x = 20

Answer 1

1) x=10x-7-7
x=10x-14
14=10x-x
14=9x
x=9/14

Answer 2

Hello!
a) 10x-x=7+7
9x=14
x=14/9
x=1 (whole) 5/9

b) 4x+5y=10x-(-5y)
4x+5y=10x+5y
10x-4x=5y-5y
6x=0
x=0

c) 33x+14=3
33x=3-14
33x=-11
x= -11/33
x= -1/3

d) x+10x-43x=20
11x-43x=20
-32x=20
-x=20/32
-x=5/8
x= -5/8

HOPE IT HELPS✌✌✌
