CAN SOMEONE PLEASE HELP ME WITH THESE 4 QUESTIONS!!! ITS IMPORTANT I WILL MARK YOU AS BRAINLIEST IF YOU GET THEM RIGHT! PLEAEEESEEE

Answer 1

Answer:

1) x=5

2)x=8

3)x=4

4)x=5/2

Step-by-step explanation:

2x=10

x=5

1/2x=4

x=8

x+3=7

x=4

-14x+14=-21

-14x=-35

14x=35

x=5/2

Answer 2

Answer:

The final answers:

1) $x = 5$

2) $x = 8$

3) $x = 4$

4) $x = \frac{5}{2}$

Step-by-step explanation:

-Calculations for every question:

1) $2x - 4 = 6$

$2x - 4 + 4 = 6 + 4$

$2x = 10$

$\frac{2x}{2} = \frac{10}{2}$

$x = 5$

2) $\frac{1}{2}x + 6 = 10$

$\frac{1}{2}x + 6 - 6 = 10 - 6$

$\frac{1}{2}x = 4$

$x = 4 \times 2$

$x = 8$

3) $3x + 3 = 2x + 7$

$3x + 3 - 2x =2x - 2x + 7$

$x + 3 = 7$

$x = 7 - 3$

$x = 4$

4) $-7x + 14 = 7x - 21$

$-7x + 14 -7x = 7x - 7x - 21$

$-14x + 14 = -21$

$14x + 14 - 14 = -21 - 14$

$-14x = -35$

$\frac{-14x}{-14} = \frac{-35}{-14}$

$x = \frac{5}{2}$
