Question

a)4x-10=2x+2 b)4x-7=8x-2 c)2x+1=4x-7

Answer 1

$a)4x-10=2x+2 \to 4x-2x=2+10\to 2x=12\to x= \frac{12}{2} \to x=6 \\\\\\ b)4x-7=8x-2 \to 4x-8x=-2+7\to -4x=5\to x=- \frac{5}{4} \\\\\\ c)2x+1=4x-7\to 2x-4x=-7-1\to -2x=-8(-1)\to 2x=8\to \\\\ x= \frac{8}{2} \to x=4$

Answer 2

a)4x-10=2x+2

4x - 2x = 2 + 10

2x = 12

x= 12/2

x= 6

b)4x-7=8x-2

4x - 8x = - 2 + 7

- 4x = 5(-1)

4x = - 5

x= - 5/4

c)2x+1=4x-7

2x - 4x = - 7 - 1

- 2x = - 8

x= -8/-2

x= 4
