Question

I NEEDD HELPPP PLEASEEEE

Answer 1

a) x = -10. b) x = 7

Explanation:

a)

2(x + 3) = x -4

multiply out the bracket:

2(x + 3) = 2x + 6.

now we have 2x + 6 = x - 4.

subtract x from both sides:

2x - x + 6 = -4

x + 6 = -4

subtract 6 from both sides:

x = -10.

b)

4(5x - 2) = 2(9x + 3)

multiply out both brackets:

20x - 8 = 18x + 6

subtract 18x from both sides:

20x - 18x - 8 = 6

2x - 8 = 6

add 8 to both sides:

2x = 14

x = 7
