3x+14=4x-6
10x+5=55
12=5x+27
-3+x+4=1-2
100 a = - 1000
3(x + -2)= -15
x+3+x+1=4(x+1)
porfa​

Answer 1

● x+8 = 15

x = 7

●5x+1 = 4x-1

2 = -x

x = -2

● x-14 = -10

x = 4

● 3x+14 = 4x-6

20 = x

● 10x+5 = 55

10x = 50

x = 10

● 12 = 5x+27

-5x = 15

x = -3

● -3+x+4 = 1-2

x+1 = -1

x = -2

● 100a = - 1000

100a÷100 = -1000÷100

a = -10

● 3(x + -2) = -15

x-2 = -5

x = -3

● x+3+x+1 = 4(x+1)

2x+4 = 4x+4

x = 0
