Question

Solve: 2x-7>3 or 4-x≤-4

Answer 1

2x-7>3 -----> x>5

4-x≤-4 ------> x
`\geq` 8

Explanation:

2x-7>3

2x-7+7>3+7

2x>10

2x/2 > 10/2

x>5

4-x≤-4

4-x-4
`\leq` -4-4

-x
`\leq` -8

(-x)(-1)
`\geq` (-8) (-1)

x
`\geq` 8

Answer 2

Steps to solve:

2x - 7 > 3

~Add 7 to both sides

2x > 10

~Divide 2 to both sides

x > 5

Steps to solve:

4 - x <= -4

~Subtract 4 to both sides

-x <= -8

~Divide -1 to both sides

x >= 8

Best of Luck!
