(10x + 4) + (5x-4) ≈ 180
solve for x and you get x≈12
plug 12 in to 5x-4 and you get 56
Answer:
x = 4
Step-by-step explanation:
3x - 6y = 18
2x + 2y = 6 -> 3(2x + 2y = 6)
3x - 6y = 18 -> Cross out - 6y
6x + 6y = 18 -> Cross out + 6y
9x = 36 -> Divide 9 on both sides.
X = 4
1. -6.2f + 2.9f = -3.3f
2. -22-4 = -26
= -3.3f - 26
Answer:
